What do you like best about the eight-character Cai Zheng?

I was born in the twelfth month of winter, and I need the help of fire. (Cai Zheng) Ding Huo was very happy to use it. Ding Ren joined the sun on the pillar of wood, which is the combination of heaven and earth. Marriage is a perfect union. So, I am happy. As for the taboo, it is because it is a foreign country. Moreover, it is taboo to be born on one's own land, but I don't know where Ding will go and live on his own land when he meets Ren for the first time.
