We think that Mr Wang’s reasoning is also open to criticism. First, in all the above materials, Li Tong mirror changbian continued funding of the treatment is the most original material, considered. Is the book begins in the period of Emperor Gaozong of Song, finish on filial piety in the Song dynasty period, but bile copper production by that time were already in production occupies an important position in the copper industry. If the period of Emperor Renzong of Song officials were ignorant of biliary copper description is wrong, it is also understandable that; but if the people of Southern Song Li Tong does not know what is biliary copper Board book for persistent “copper cast iron hybrid” means without textual clearly unreasonable. Although the existing mirror changbian continued funding of the treatment and copper recorded no bile in the content, but this fact does not prove that Li Tong on biliary copper does not understand. Government began vigorously implementation bile copper method production is in Song Zhe Zong Shaosheng years and Emperor Huizong were ruled period, and existing of continued funded treatment pass mirror changbian under precisely missing zhezongyuan y result u@ ① eight years (1093) July to Szabo Saint four years (1097) March of content and emblem were, and Chin were two towards of all content, cause we cannot from existing of continued funded treatment pass mirror changbian under in the see about bile copper production of recorded. However, in the group book Causo Zhang Ruyu refers to a now lost missing mirror changbian continued funding of the governance of the content, which explicitly mention the gall of copper. Citation following: “(Sung Ning five years zhongshusheng prospecting will all road revenue copper number) annual about received all color copper more than 6.6 million kg, old copper Tin about received more than 4.6 million kg, bile copper about received 1 million kg sth sth” immediately subsequently of a article material is from are has lost lost of continued funded treatment pass mirror changbian under content, material records has Kaifeng yin and lifting Kyung Ki money prison Song Qiaonian in Grand II years of Shang statements, which more is repeatedly mentioned “seep through copper coins (with bile copper casting of money)”, because bile copper cast money cost low, Song Qiaonian also recommendations: “hubu available of number, can seep through copper coins Xia all road order yiyangzhu. “ (set volume 60 after the fiscal deficit · coins class) you can tell from these records, Li Tong’s original book was a new species of biliary copper, bile of copper and copper he should know the difference. Based on this, should not be “copper-iron complex casting” as “error” of the genus. Second, the casting of main raw materials are copper coins in the Song dynasty, auxiliary materials are lead and Tin, copper coins of the Northern Song dynasty maintained a basically “is their agent, six copper, lead, Tin Sam, there are odd win” proportion of materials. During the Southern Song emperor Huizong later to owing to lack of copper copper ore, and mass production biliary copper, cast copper money raw material also used in biliary copper. The full text of the Song Shi said “true copper-third and to the” the implication is that reflects the people still have the traditional concept at that time, only after mining of copper smelting are recognized is “copper”, also reflects the number of mine copper only three-tenths per cent of all copper raw materials used for money. This figure and the continued funding of Hueschen in the treatment of mirror changbian money formula only coincidences on the proportion of cases only, connotation is different. Hueschen says “copper two-iron six minutes”, not mine copper and biliary copper ratio, but rather to change the proportion of raw material and cast copper coins, will remove lead and Tin, adding the iron as the main raw material, six-tenths per cent of all cases, strong copper accessories, top three-tenths per cent of all cases. Third, the mirror changbian continued funding treatment referred to in “medicine mixed cast iron and copper” was intended also to understand it from another angle. Due to the end of the melting point of high melting point of iron, copper, put together two kinds of raw materials to melt, inevitable copper melting of iron is not out of sync, Hueschen said in the proposal of “medicine” is probably in order to address this issue and joined some flux to lower the melting point of iron. However, this formulation is fundamentally unworkable plots for iron, copper, were naturally occurring during the test, “miscellaneous iron stream astringent and not the” problem. In addition, limited by production conditions at that time, biliary copper production should be in the tank water (or gall) abundant in the mining area, and continued funding of the treatment of mirror changbian just mentioned in Jingshi Xu Shenchu, money directly in Jiangzhou after testing. These two places is only money sites, does not produce biliary copper, if Hueschen materials for biliary copper were used as money, rulers must first biliary copper in some production out of the mine, then transported to the metropolitan or Jiangzhou money, but for such an important production activity, North but made no mention in the records of the period of Emperor Renzong of Song. Given the above analysis of several points, I think the period of Emperor Renzong of Song Hueschen in the metropolitan and Jiangzhou money test should be used as raw materials for iron and copper, and bear no relation to bile production.
Third, the period of Emperor Zhezong of Song by biliary copper promotion
According to Su zhe the Longchuan records contained, songzhezongyuan y result u@ ① period, I wish there is a businessman, to give the Government a secret law – biliary copper law. At that time, Su zhe hubu Assistant Minister, “a businessman in hubu, a secret method to iron for copper copper sulfate. (Su zhe) called closely question saying: ‘ banned by ru, secret law. Try this if is to the Crown, must be broad, Yu Man cannot, will bring others to help you, you all know, non-complex secret, effect of the ban, this will be all over the world. And my Palm Court plans first to row by indiscriminate mess, I don’t. ‘ @ ② f ǔ @ black out its people, that call on provincial words, everybody confused, try chopping the Sabre, and thereafter was accomplished. “ (volume five not heard b ì @ ④ method can to iron for copper who under) Su point any hubu Assistant Minister of time is in Yuan y result u@ ① II years (1087) November to Yuan y result u@ ① four years (1089) June  (volume 407 Yuan y result u@ ① November 2 methyl Xu; volume 429 Yuan y result u@ ① June 4 Ding not), visible this segment period song Government of rulers still not understanding bile copper production and by can up to of role, bile copper production also was called” secret method “, still is civil privately for of small range production.
Biliary copper no longer be promoted as a secret law banned by the Government, is in raozhou Dexing County man Zhang Qian, Zhang Jia wrote of the leaching of copper slightly to the father and son Song Zhe Zong Shaosheng years after the Imperial Court. Author of on the leaching of copper slightly and writing times, people and Zhao Bo Chen Zhensun of the Southern Song dynasty recorded in much the same. Chen Zhensun of the Zhai stated in solving index containing such data as the editions, illustrations, commentaries and sources of a certain book or certain publications: “the copper slightly immersed volume, Zhang Jia, called ‘ grassy marsh of dexing ‘. Shao shengyuannian (1094) sequence, cover flooding bile Tetsushige beginning of copper. A, progenitor of the politics of public. “ (volume 14, of the hybrid arts class) Zhao Bo in the outline of the interception games record of telling about the Xinzhou qianshanxian introduced in Shao during the Saint Gall when copper production scenarios mentioned:  (volume five of the interception outline of games in mind)

D ī @ ⑤ springs pool, soothing pools to ditch, cloth and iron, to saturate, iron and copper into sth These two materials are simply pointed out that Zhang Jia bile test of copper to the Imperial Court and offered books and persons, thereby missing the merits of the father of Zhang Jia Zhang Qian. In fact, during a test in biliary copper production by, Zhang Qian’s merits is maximum. Wang Xiangzhi in the territory of Sheng JI Chu Xiaoxi of the Changsha records are referenced in (Note: for the Changsha Chu Xiaoxi 11 volumes of the journal, see volume 204 of the art of the Song Shi of the three. ) Record, saying: “long Sha Zhiyun: ‘ start, iron for copper raozhou Zhang Qian of the wonderful, to mail call on Jue Xianzhi. Imperial Court before its method in Qianshan, and Rao of rainwater in puddles of Hing Lee, Shao (Shum) of water are submerged method. ‘ “ (volume two or three of the South East · raozhou · under scene) a few years ago, dexing, Jiangxi province discovered the tomb of Zhang Qian line-shaped tablet, the inscriptions in the first year of Grand view of Northern Song dynasty (1107) in March, the inscription reads: Zhang Qian” reading of the Shen Nong tasted book of iron for copper water leaching of copper sulfate, try xinran. The saying: ‘ this also benefits the operation ‘. Life offers its mail. “(Note: it is reported that the inscriptions more than 3,000 characters. This tablet is saved in Dexing County Museum. )  this inscription shows, the Shennong Bencao Jing, Zhang Qian from down in the record book gain awareness of biliary copper, after their test written in the book of leaching copper slightly, asked his son Zhang Jia turned over the Imperial Court, biliary copper to after this promotion.
Addition to the above song recorded outside, of the late Yuan and early Ming human crisis article wrote of the leaching of copper slightly sequence, introduced the Song dynasty who wrote the book of the leaching of copper slightly and Dexing County leaching copper, most detailed content. He wrote:
(Yuan dynasty) Division for dexing in Fujian vision comfort, adjustable Crown Metropolitan examination full, more coins by the national party, offered precedent of the leaching of copper slightly in the DPRK. …… Trip to coins, so the drums cast of infinity, copper production is limited. Acting is the leaching of iron, copper, and Gong Bo received less cost. …… In Shao this book, and its assertion that, covers y result $ u@ â ‘ first year.

Is the book, first presented little acting Grand name down the House, to delegate his daughter donated Grand name strips, a surname Fu cheng Zhong Fu King name. Sun Assistant Administrator of a surname Zhong Gong Huidao sh his @ ⑧ sequence records. (Note: text errors in the original text, and the Jiangxi General Annals Volume 162 introduction recorded in the Miscellanies repair dangerous effect on the leaching of copper slightly sequence of corrections. )  (volume three of the leaching of copper slightly sequence)
Judging from the dangerous effects of the genus, he saw the leaching of copper slightly in this book contains a sequence of Zhang Qian’s great-grandson Zhang Dao, showing that this book has offered is not Zhang Qian Shao shengyuannian version of the Imperial Court. Family origins of Zhang Dao and Zhou wenzhong set will be an official career  (mid-left a Temple University Senior Minister volume 64 of the doctor’s Assistant Administrator presented a surname of Zhang Zhongding Gong Dao tombstone), and the Song Shi,  (volume 382 of the Zhang Dao) are recorded: “Zhang family of dexing, after Prime Minister Tang @ ¢á … Public (Zhang Dao) great-grandparents name intermediate pass straight by Shi Lang, presented Prince Edward little …. Zu Pan, Yuanzhou wanzai County main book, presented Prince Edward a surname … Gong Huidao, sth Governance and for eight years (1118) tingshi sth Son of an affinity for RTHK’s third. “One of the Zhang Dao Yu Hui and Chin high, filial piety, and dynasties, in the first year of Longxing (1163) moved to Assistant Administrator, to old disease do not worship, chapter remonstrations, Bachelor of science in addition to the House of the Senior Minister, lifting concept of longevity and Chamberlain read. After Shi. Stroke two years on dry road (1165), year 75, IK Chung. Based on the life of Zhang Dao to judgment, Zhang Dao as the leaching of copper slightly preface should, after he entered the career of the late Northern Song dynasty to the Southern Song dynasty between the early years of the dry road. Dangerous effects in the leaching of copper slightly sequence mentioned in the “spring two 30″ name and “and the spill of more than five years of rain spring, the dip to the maximum” sentence, likely came from Zhang Dao as the leaching of copper made slightly more content in the sequence. If so, 138 32 spring groove of bile dipped iron scale might not just the spring stage of Northern Song dynasty (Note: the Japan zhongdaomin, although not to research, but mention 138 32 spring gully Dexing County Herald the most prosperous period (late Northern Song dynasty). See what China た の evolution る wet your copper, Toyo Journal Volume 27 3rd, 1939. ), Also extend to the Southern Song dynasty, but raozhou biliary copper output to Song Weizong governance and five years as the highest.
Tetsushige of copper sulfate of copper records have existed since ancient times, North of Emperor Renzong of Song period had also conducted an experiment, why only to the period of Emperor Zhezong of Song popularized it? This is the objective needs of the situation, and Zhang Qian also is closely related to the efforts of father and son. The early Song dynasty, while the copper mining was gradually rising trend, copper supply and demand contradiction is not sharp; on the other hand, the Government has long taken a “copper-ban” measures, I am afraid that new production technology to circulate, on Government monetary policy difficult to control the situation; Furthermore, biliary copper production theory is still in trial stages. During this period, both objective factors, are subjective factors, also do not provide a basis for bile produced by copper. When Emperor Zhezong of Song succeed to the throne, has faced a copper production ended during the reign of brilliant development stage and entered a period of sharp decline, this situation resulted in a large quantity of money supervision of sharp reduction of waste and the amount of money. Song dynasty Government under enormous pressure, urgently ways to recover copper production, increasing production. It is in this situation, Zhang Qian after father and son of painstaking tests, systematically summarized bile production methods, and dedicated to the Imperial Court of the leaching of copper slightly more proactively. Demand for objective and subjective efforts to get the perfect combination. Thus, in the song and strong advocate of the Government, bile produced by copper rapidly by promotion.
