In acupuncture treatment, it is not only necessary to select the appropriate acupoints, but also to select the appropriate treatment time, in order to obtain a more effective treatment with less effort. In the long-term medical practice of ancient Chinese physicians, they discovered the law that different acupoints are opened at different dates and times, and summed up a set of song formulas, which is "Xu's Ziwu Liuzhu Song of Fixing Acupoints on Time by Day". This application is based on this song formula. , The date and time of opening acupoints are displayed in the form of graphs, so that the treating physician can inquire when needed.
