1. Introduction
The discovery of Mawangdui Tomb of Changsha is one of the most significant events of the 20th Century in both archeology and culture world, one of the most important discoveries of this excavation is a group of ancient medical books which in the following chapters will be addressed as Mawangdui medical books. These medical books were all lost books, that is to say, there aren’t physical versions survived today, due to the abstruse and sophisticated contents, those books aroused widespread concerns since then. For the past forty years, researchers have accomplished fruitful results studying them, yet retrospective studies are still rare. It has been four decades since those medical books had been excavated, so we collect the relevant research results and classified them into different categories in order to have a more comprehensive and clear understanding for the early studies, then we can summarize some problems that still exist and propose some possible solutions.
By the end of 1973, the eastern outskirts of Changsha, Hunan province, Mawangdui III tomb unearthed a large number of silk manuscripts and some bamboo slips. Part of the bamboo slips can be classified as prescriptional documents; they have about twenty thousand words, covering diagnostics, acupuncture, Jingmai-xue, pharmaceutics, health preservation and fertility studies. Since neither titles nor name of the authors can be found when they were unearthed, so the research group divided all those books into fifteen kinds and named them as follows: Hand-foot-11 by Moxibustion (hereafter called Zu Bi足臂), Yin and Yang Moxibustion by 11 book A (hereafter called Yin Yang book A阴阳十一脉灸经), Pulse Law (脉法), Death Syndromes of Yin and Yang pulses (hereafter called Death Syndromes阴阳脉死候), Prescriptions of fifty-two diseases (hereafter called Prescriptions病方), Que Gu Shi Qi (却谷食气), Yin and Yang Moxibustion by 11 book B (hereafter called Yin Yang B阴阳乙本), Guide map (导引图), Healthcare Prescriptions (养生方), Miscellaneous Cure (杂疗方), Births book (胎产书), Ten Questions (十问), Yin and Yang in one (合阴阳), On Principle of Universe (天下至道谈), Miscellaneous banned prescriptions (杂禁方). And the Miscellaneous banned prescriptions were written on wooden slips, Ten Questions, Yin and Yang in one, On Principle of Universe were copied on silk book.
2. Review the studies for the Past Four decades
Mawangdui medical books have been explored for forty years and researchers have achieved many remarkable results studying them. Based on writer’s statistics, by November 2014, there were already more than ten monographs and hundreds of papers in related studies, we are now going to review all those domestic and international research results retrospectively.
2.1. Domestic research
2.1.1
. Informative Monograph
In 1974, a research group was formed to analyze Mawangdui medical books and that very Prescriptions of fifty- two diseases (Mawangdui Han Danasty Tomb bamboo books research group, 1979) was published at the same year, another book published at the same year was Ma Wang Dui Han Tomb Texts―Derivation Graph (Mawangdui Han Danasty Tomb bamboo books research group, 1979) . In 1985, Mawangdui Han Tomb Silk Book Ⅳ (Mawangdui Han Danasty Tomb bamboo books research group, 1985) was published and this book contained all the charts and explanations of Mawangdui medical book and corrected certain parts of the previous edition also. The publication of this book had significant meanings, it provided researchers authentic interpretation for the past forty years; Changsha Mawangdui Han Tomb Field Archaeological Report Writing (Hunan Institute of Archaeology, 2004) , came out in 2004, with explanations of the following ones: Ten Questions, Yin and Yang in one, On Principle of Universe, Miscellaneous banned prescriptions; In 2014, The Integration of Mawangdui Bamboo silk books (hereafter called The integration) (Qiu Xigui, 2014) came out, this book rearranged and interpreted all documents patterns and annotations of all the documents in this subject, its also announced the latest research results, included the then latest results. It’s the most accurate and comprehensive edition.
2.1.2. Research Monograph
Right after the publication of the rearranged charts and interpretations of the medical books, researches in many countries took great interest in them. At the domestic level, there are five main monographs which studied on those medical books from the linguistic angle. In 1988, Mawangdui Medical Books Test Notes (Zhou Yimou & Xiao Zuotao, 1988) was first published, this book had a complete style and clear interpretations yet also had some questionable proofreading; In 1992, Interpretation on Mawangdui medical books (Ma Jixing, 1992) was published and this book did a thoroughly research on repairing and correcting the residual texts; Proof and Explanation about Mawangdui Medicine books (I) (II) (Wei Qipeng & Hu Xianghua, 1992) published in same year, this book did a basic introduction from medical standpoint yet didn’t lack of interpretation; In 1995, Mawangdui Medical books (Lu Zhaolin & Huang Zuozhen, 1995) was published and this concise book didn’t discuss too much about pervious contentious issues; In 2014, The Collation for Bamboo and Silk documents (Zhou Zuliang & Fang Yilin, 2014) was published and this book did a thoroughly proofreading and corrected some mistakes, this book is available for reference in studying those medical books; In addition all of those, The Additional Interpretation For Prescriptions Of Fifty-two Diseases (Yan Jianmin, 2005) supplemented some of the missing parts yet the proofreading were not rigorous enough.
Besides monographs, related papers can also be found in some medical periodicals such like the Mawangdui Medical books (Mawangdui medical books research group, 1980 & 1981) and Mawangdui Research Collection (Hunan Provincial Museum, 1994) . Among all the unearthed books, Mawangdui medical books are the focus of most attentions, such as Zhangshou ren’s Medical On Set (Zhang Shouren, 2000) studied the book Prescriptions of Fifty-two Diseases; In Bamboo-silk Drug Name Research (Zhang Xiancheng, 1997) Zhangxiancheng categorized the drug names comprehensively; In Medical Term research in Qin-Han dynasty (Zhang Xiancheng, 2000) . and Glossary of medical term in Qin-Han Dynasty (Zhang Xiancheng, 2002) scholars also studied medical terms among those unearthed medical books thoroughly and comprehensively.
2.1.3. Papers
Because Mawangdui medical books were transcribed either on bamboo or silk and many parts had been severely damaged when they were dug up, plus, lacking of physical versions also contributed their research values. Besides monographs, single papers discussed from specific angles are also many. We are now going to illustrate all of the early studies in different respect.
1) Documentaries articles and other reference studies
Early before the publication of Mawangdui medical book’s research materials, the research group had already published several relevant articles. In 1975, the sixth edition of the Journal Cultural relic published The Interpretation of unearthed Mawangdui Medical books I, this article released the annotations of Guide Map, Que Gu Shi Qi, Yin and Yang, Pulse Law, Death Syndromes; In same year, the ninth edition published The Interpretation of unearthed Mawangdui Medical booksⅡ, released the annotation ofPrescriptions; In 1981, Zhoushirong published The Interpretation of Changsha No.3 Han Tomb Bamboom book Healthcare Prescriptions and this article released the annotations of Ten Questions, Yin and Yang in one, Miscellaneous banned prescriptions. There are also some articles trying to explain and interpret those medical books like Huangchangjie’s “阴阳脉死候”释译, Mao Liang, 古医书〈脉法〉诠释, Wu Zhichao, 〈却谷食气篇〉初探, Liu Shijing “却谷食气”试释, Wei Qipeng 帛书〈却谷食气篇〉研究etc.
2) Studies on words
As no physical versions of those medical books survived and no one knew their existence till few decades ago, what’s more, all the characters were written either on bamboos or silks, so identify the original scriptures is really difficult. In order to understand them better, a large number of scholars joined into this team. Order generation linguists like Lu Zongda (Lu Zongda, 1981) , Qiu Xigui and newer generation ones like Liu Zhao, Zhang Xiancheng, Chen Jian, and Meng Pengsheng. Professor Qiu made great contributions in translating those books (Qiu Xigui, 1987) and Meng Pengsheng made lots of detailed and convincing researches too (Meng Pengsheng, 2003) ; Through carefully proofreading the photos; Chen Jian (Chen Jian, 2013) supplemented the interpretation from the original text, so that the “病方” and “养生方” have more accurate and reliable interpretations than before; Liu Zhao刘钊 studied 牧牧 (Liu Zhao, 1994) in Zu Bi足臂 and龟、虫 (Liu Zhao, 1997) in Bing Fang病方 with phonology theory and medical knowledge then came to the conclusion that 牧牧 is supposed to read as 瞢瞢 and 龟、虫are supposed to be 桑虫. Some famous Chinese physicians like Shi Changyong史常永 (Shi Changyong, 1993) , Zhao Youchen赵有臣 (Zhao Youchen, 1981) , Ren Yingqiu任应秋 (Ren Yingqiu, 1984) , He Zongyu 何宗禹 (He Zongyu, 1981) are also engaged in this effort and their results are also contribute the current research from different angles.
All those researches were mainly focused on naming the drug names, because lots of drugs had been named as same names which made reading those medical books became harder, so studying their names are extremely important. So far as the status the most foremost expert is professor Zhang Xiancheng, besides all those books we mentioned above, he also wrote many articles which combined with critical interpretation, phonology and medicine knowledge. Take简帛医书药名释读续貂 (甘肃中医学院学报1994) for example, professor Zhang corrected five groups of interpretations of drug names, following are the conclusions: ①?
实,兔
, based on what was written on Shuo Wen, ? is an E word and the transcriber substituted 菟 with ? and made it as ?
实, 
and芦 both pronounced as 卢 so their sounds can be altered, plus, 实 means “the seed” which explained why ?
实 is 菟丝子; what’s more, 兔 is the phonetic element of 菟 which also explained 兔
is 菟丝子; ②禹灶，禹熏 and 乾夸灶 are 伏龙肝: because 禹 is the borrowed word of 矩, and 灶, 熏are 灶土, 熏土, and 夸 is 大 which explained why the above three are all 伏龙肝; ③要苕 is 紫葳: because of pronunciation changes, ?苕 became 要苕 and the book Er ya can also prove that ?苕 is 紫葳; ④?骀and 黄蜂骀 are 蜂子: ? and 蜂 are gu jin zi (ancient and modern word), 蜂骀 and 蜂子 are result of pronunciation changes; ⑤遗弱 is the fresh human urine: by the methods of exegetics 遗 has the meaning of “to excrete” which is why 弱 means 溺 and 遗弱 means “fresh human urine”; ⑥牡狗 and 牡蝼 are 蝼蛄: 杜 miswrote as 牡, and 杜狗 and 杜蝼 are two written forms of one pronunciation, they are all synonyms of蝼蛄. Another article马王堆佚医书释读札记(《简帛研究》1996) studied seven words which were either misinterpreted or didn’t be interpreted in Mawangdui medical books, 再食
、?
、?、?、并符、?、?.
Besides those, 简帛医书中的中药异名(《医古文知识》, 1994) collected 57 synonyms from the medical books and marked their phonology positions, this helped in a significant way to understand Mawangdui medical books; 马王堆医书药名“汾?”试考(《中华医史杂志》, 1996) proved 汾? is 香蕈 from both exegetics and medical perspectives yet successfully solved this problem; Similar articles also have马王堆医书药名试考(《湖南中医药大学学报》, 1996), 马王堆医书疑难药名考释二则 (《甘肃中医学院学报》, 1996), 简帛医书中的中药异名(续一)(《中医药文化》, 1997 and〈马王堆古医书考释〉补正, (《湖南省博物馆四十周年纪念论文集》，湖南教育出版社, 1996) etc.
Speaking of naming drugs, another name we must mention is Sun Qiming, since last eighty’s he published series of papers discussing drug names about Prescriptions of fifty-two diseases, mainly includes: 为〈五十二病方〉“久脂”补注(《中医杂志》, 1982), quoted from Yupian (玉篇) and Bielu (别录) and proved 久脂 is 膈脂 which is “cool-preserved lard”; 〈五十二病方〉“膏、脂”释义 (《中成药研究》1983), this article quoted from ShuoWen (说文) “戴角者脂，无角者膏” and then distinguished the meaning of 膏 and 脂;〈五十二病方〉仆?考 (《中成药》, 1983) quoted from Bencao Gangmu (本草纲目) and interpreted 仆? as 蜗牛;〈五十二病方〉骆阮、白苦、苦浸考 (《中成药》, 1984), based on the explanations from some definitive ancient dictionaries and combined the actual curative effect of medicine then reached the conclusion that 骆阮, 白苦 and 苦浸 are all synonyms of 苦参;〈五十二病方〉鹊棠考辨(《中华医史杂志》, 1995年4期), this article believed the character of 棠 is the miswriting form of 巢 and 鹊棠 is supposed to be 鹊巢;〈五十二病方〉“麋芜本”别释(《中华医史杂志》, 1997), this article listed several entries from Shan Hai Jing (山海经) and proved 麋芜本 was an extinct plant; 帛书“?荚”别释(《中华医史杂志》, 2000) and ?荚考辨(《医古文知识》, 2001), those two articles thought that ?荚 is the miswriting form of ?茅 and ?茅 should be 萧茅, meaning “twitch-grass which had been used as sacrificial offerings”;〈五十二病方〉药物选释(《浙江中医药大学学报》, 1987), this article studied several drug names of “冥蚕种”.
As for Guide map (导引图), Shentao published three articles on the first, third and ninth issues of Wenwu (文物) respectively in 1979, they are 谈西汉帛画〈导引图〉中的“猫蹶”, 谈西汉帛画〈导引图〉中的“引?积” and 谈西汉帛画〈导引图〉中的“引烦”, those three articles discussed 
, 引?积 and 烦 three surgical methods. Shen thought

3. Existential problem and possible Solution
3.1. Existential Problem
Ever since its excavation, researchers have done lots of remarkable achievements, yet we are still facing some problems which summarized as follows:
3.1.1. Interpretation Is difficult
For the past forty years researchers have been diligently working on collating and interpretation and achieved remarkable results, however, due to its multifarious contents and used to be severely derogated, plus, the variant forms of characters, there are still lots of doubtful words and phrases need to be interpreted. Besides, the physical versions of those medical books were lost in history so it is almost impossible to find their related reference books which can explain the difficulty of interpreting them. For words which have already been interpreted, due to the limited materials the correctness of the conclusion also needs further validation.
3.1.2. limited research Method
Not only researchers must have in-depth knowledge on philology, they must also familiar with medical theory due to the peculiar particularity of those medical books. Experts from diversified fields have done a large number of researches, however, generalists who are proficient in all those referenced subjects are still rare which contribute the limitation of current studies.
3.1.3. No Comprehensive Treatises Have Been Made Yet
Research results about Mawangdui medical books are massive both at home and abroad, however, those books and articles are scattered across different journals around the world, not to mention their long span of publishing years which explained why it is so hard for researchers to have a clear yet full-scale perspective. So a comprehensive treatises which collects all the previous studies is in urgent need now.
3.2. Possible solutions
Based on the above discussions and some of the problems we are still facing, we now come up with some possible solutions, hopefully can be useful.
3.2.1. Integrating andcollaborating
Like we discussed above, researchers must be experts at both sides, so the central task at present is to integrating different fields and cultivating all-round talents, only by doing so can we break down the current barriers. The newly published Ji Cheng is exactly the very book we need, it has high quality interpretation and standard charts. The publishing of this book has a realistic and reference meaning to the study of Mawangdui medical books. So closer cooperation and more academic exchanges are still needed, only by doing so can we can find innovative solutions to difficult issues and achieve ideal results.
3.2.2. Strengthening international exchanges and Cooperation
The excavation of Mawangdui medical books not only aroused the interests of Chinese scholars, many Japanese and American scholars are also put great efforts in it. However, different cultural backgrounds may also differentiate people’s perspective, which is why we should give enough attention to all the results domestic and international. Therefore, more international symposiums need to be held if we want achieve further and comprehensive achievements.
3.2.3. cultivating and enlarging
The study of Mawangdui medical books requires all-round talents yet people like that are still rare now, so we need to cultivate a number of highly qualified personnel. “we need to find out more young people who have intense interest in unearthed medical books and solid foundation on medicine and ancient Chinese Documents, we can either send them to graduate school or help them further study the related knowledge. Later on they can apply what they learnt from school to the actual research and enhance their abilies.” (Zhang Ruqing, 2008) .
3.2.4. summarizing and synthesizing
Only one book Ji Cheng cannot include all the previous studies due to its limited length, which further emphasized the importance of summarizing and synthesizing the early researches. According to the authentic news, Professor Zhang Xiancheng and his team from Southwest University is doing this now, we look forward to their success.
