What is a couple star?

First of all, the word you said is a fortune-telling term, which means that the woman takes me as her husband and the man takes me as his wife. Here, xiangke refers to the xiangke of eight yen for husband and wife. For example, "water can put out the fire." Among them, Party A and Party B are wood, Party C and Party D are fire, Wuji is earth, Geng Xin is gold, and Ren is water. For example, a man's eight-character yen is nonyl or decyl, and Bing Ding is his wife. If a woman's eight-character yen is nonyl or decyl, Wuji is her husband star.
