What do you mean by opposing each other?

It's a feng shui term, which is often said in daily fortune telling.

Ten taboos:

That is a taboo against dragons and evil spirits; Second, avoid the stone wrapped around the rock to grab the dragon; Three taboos are guilty of fierce sand and water; Four bogey points blow away against the wind; Fifth, don't beat your chest with a sand probe; Six taboos against sand crime are ruthless; Seven don't avoid water, shoot against the bow; Eight don't avoid water to create great evil, nine don't rush to make trouble, and ten don't rush to fight back. Ten taboos are all evil.
