[Hai Shang Xin De Shen Fang written in Chinese in Vietnam]

"Hai Shang Xin De Shen Fang" is an ancient medical book written in Chinese by Li Youzhuo, a famous doctor in the Post Li Dynasty in Vietnam. The book was deeply influenced by "Feng Shi Jin Nang Mi Lu", a representative book of the Warming School (Wen Bu) written by Feng Zhaozhang in the Ming and Qing Dynasties. By comparing and examining the two books, it was found that forty-five out of the sixty-six prescriptions in "Hai Shang Xin De Shen Fang" came from or were simply copied from "Feng Shi Jin Nang Mi Lu", or were extracted from the medical cases from "Feng Shi Jin Nang Mi Lu", or were changed the name but kept the ingredients the same. The other twenty-one prescriptions followed the examples of "Feng Shi Jin Nang Mi Lu" and presented new prescriptions. It can be seen that "Hai Shang Xin De Shen Fang" reflects the extension spread, and development of the academic thinking of the Warming School (Wen Bu) in the Ming and Qing Dynasties in Vietnam and demonstrated the Chinese cultural origin of Vietnamese traditional medicine.
