The influence of Liu Yao calendar

"Six obsidians" stipulate bad luck and fortune, and many of them are related to gambling. It was originally used by gamblers to decide whether to bet or not. Therefore, in today's Japan, the betting lottery tickets printed by state-owned gambling institutions will also be printed with "Six Obsidian".

Among many Japanese calendar annotations, Liu Yao is a very famous one. General calendars and handbooks (a kind of portable diary) are marked. It has a wide influence on Japan today. It is mainly used as a reference for coronation, wedding and funeral, such as choosing "Daan" for wedding ceremony and avoiding "friends" for funeral.
