Determining Yongshen based on seasons only means adjusting Yongshen, and Yongshen can be divided into many types, including supporting and suppressing Yongshen, clearance Yongshen, etc. Yongshen are analyzed based on the entire eight-character combination, that is, year, month, day, hour, lack of Not even one.
