Don't take this incomplete Zhouyi as an authority.
Eight characters are spatio-temporal information. For example, those born in drought and cold are born in Xia Dong for two seasons, lacking the five elements of microclimate. The eight-character Universiade is also the time and space information derived from the moon, not to mention the fleeting time. It was decided at birth that a small piece of jewelry can change time and space. Is this not a joke? If the eight characters can be changed, there are still poor people.
