Generally speaking, Tangtouqu pays attention to melody, that is, it summarizes the melody that is convenient for everyone to remember rather than the main content (composition and efficacy) of the prescription. Some books in Tang Tousong will be accompanied by prescriptions and explanations, pathogenesis and so on. But they are also simplified and mainly general. However, the prescription science system explains the prescriptions in detail, and there are folk songs at the end of the book.
Analogously, if "Prescription Science" is compared to Chinese, then "Tang Tousong" is equivalent to a summary book of "Chinese", and the formula of Tang Tousong is equivalent to the central idea or paragraph effect of an article (so the book "Tang Tousong" is also divided into advantages and disadvantages). You can't learn Chinese with an explanation book, can you? Therefore, Tang Tousong is used to understand and remember after you have studied prescription science.
Therefore, to learn recipe science, we should read books with detailed contents, such as recipe science, and then use Tangtouge to help us remember.
