Hello, the constellation is a fortune-telling thing for westerners. Because westerners don't have a lunar calendar, we should first convert the birthday of the lunar calendar into the solar calendar, and then look up the constellation table.
If it is the lunar calendar 198 1 year 1 month 13, it will be converted into the solar calendar 198 1 year 12 Tuesday, which is Sagittarius;
If it is Gregorian calendar 198 1 year 1 1 month 13, it is Scorpio.
