Who can help me see what these symbols are called and what they are used for (for example)

This is a centralized Taoist symbol commonly used in Taoism, which can be used to drive away corpses, town houses and protect the body. From the left, the first "pardon evil spirits" means that evil spirits can be forgiven if they behave well here; The second "pardon the general to come here" means that the general in charge of the underworld holds great power and can command ghosts. When the general arrives, the ghost will obey. This is an order from a ghost. The third "forgive signing with you" has two meanings. First, it protects the lives of the dead. Second, it banishes ghosts and keeps them away from here, so run for your life. The fourth picture "Forgive the Evil Ghost" is different from the first picture. Taoist symbols are written in different ways, and many of them have the same name. This is a gentle pardon for ghosts. The first one is more serious. The fourth one is milder. These two symbols have the same meaning.

Have a nice day!
