What is the Five Elements Earth Tomb?

Among the five elements, Jin Mu has a tomb, while Tuwang has no separate tomb. Opinions vary. Some people say that the earth follows its mother, and the mother is fire, so the tomb is in the tomb; Some people say that the land is in Kun Gua, so it is in Kun Gua, so it follows its son-Jin. I think it's immortal and ugly! Reasonable!
