Is it true that a fairy possessed a birthday?

Generally speaking, the eight-character fortune-telling can at most show that some people are saints in a certain life, correct others and live like wild cranes in the clouds. This kind of people generally want to jump out of yin and yang, so they have the desire to cultivate immortality. However, immortals don't possess themselves, and eight-character fortune tellers don't care about such things. At most, it is a wife, a rich boy, a long life, and good luck is good and bad. Only Taoist priests and witches can tell the story of immortal possession.
