However, the ancient books of Chinese medicine are vast, and many books have become independent books because of repeated wars, moth-eaten fires, serious damage and loss, but people want to see them but can't get them; Some are distorted because of copying errors, which brings a lot of doubts and puzzles to users; Even the widely circulated ancient books are difficult to find and inconvenient to use because of their different engraving methods from modern times. All these have brought many disadvantages to the research, promotion and popularization of traditional Chinese medicine. In view of this, China Society of Traditional Chinese Medicine, Hunan Electronic Audio-visual Publishing House and Jiahong Technology Development Co., Ltd. cooperated hand in hand, and after years of planning and production, they combined ancient culture with modern technology to launch the CD-ROM of Chinese Medical Code.
