How to understand mutual conflict and mutual harm?

Opposition is opposition, such as meridian rush, north-south rush! If you go forward, he will push you back!

Mutual punishment means that the other party is in charge of you, such as the jailer who is in charge of the prisoner!

Hurting each other means that the other side hurts you, for example, water can put out the fire and the enemy will attack!

These are all terms in physiognomy, magic door and geomantic omen, just tips for life and truth!
