This eight-character character still comes from the stem of the date of birth, Kun Zao: Ren Yin Chen Jia Yi Si Ren Wu. It's just that the Universiade is different, because the seasons in the northern and southern hemispheres are opposite, and the arrangement of the eight-character Universiade is based on the rose. In the 1990s, it was proposed that the Universiade should be male and female, and the fate of women in the southern hemisphere was opposite to that of women in the northern hemisphere, that is, the fate of men in the northern hemisphere was the same, and the Universiade was B, C, D and D.
