1, mutual, such as living alone, men and women love each other. This is easy to understand.
2, handed down from generation to generation, for example. Hand over all the behaviors that happened from A to B, from B to C, and from C to D in turn.
3, single phase, such as, good words, truth. What one party does to the other is single-phase. The "phase" of "believing" usually refers to a single phase, such as I don't believe it. I don't trust anyone. But occasionally they use each other.
4. An ancient superstitious activity. Add and subtract strokes with Chinese characters, disassemble radicals or disrupt font structure, and stick them on people to calculate good or bad luck.
