Guardianship is an amulet, which means protective amulet. It comes from Japanese. There are feng shui, luck, luck, beauty, bells, cause and effect, fortune and so on.
In Japan, watchkeeping is a symbol of desire. Guardianship was first used to ward off evil spirits, and gradually derived from traffic safety, safe production, happy marriage, study and health. In the early days, the monks in the shrine wrote the names of the gods on wooden boards or pieces of paper, then put them in small cloth bags and sold them to believers who came to visit the shrine. This is the earliest garrison.
Nowadays, Japanese people, especially women, buy and replace the body guard every year. For example, on the eve of entering a higher school or a competition, you will buy a qualified or successful guardian, during pregnancy, after the birth of a child, an elderly person will buy a long-lived guardian on his birthday, and a lover will buy a guardian.
