What's the name of the token in and out of the palace?

Tokens entering and leaving the palace are called combinations.

Divided into two parts, one in the hands of the guards guarding the palace and the other in the hands of people who want to leave the palace. Whoever wants to leave the palace must go to the guards guarding the palace with the matching symbol to check whether the matching symbol is a perfect match. The token is divided into two pieces, and the two cards can be combined into one, which is a special release certificate for the palace and the capital at night.

brief Introduction of the content

Token is one of the most important Taoist instruments in China. Taoist keepsakes are mostly wood, with a long shape, bent up and straight down. The style of the token was introduced in the book Du Ji Dacheng written by Qing Lingbao in Ming Dynasty, in which the dragon blade was carved on the front and the lightning rune was written on the back.

There is also a paragraph saying that when the right token was struck by lightning, it was five inches long, two inches wide and five points thick. Choose an auspicious day and make it according to the formula. Twenty-eight names were announced around, which means that the token was made of jujube wood that had been struck by lightning according to Taoist rituals. The four sides of the token are engraved with the names of twenty-eight stars, which should be collected in the toolkit after production.

The use of cards in the ancient military, as a symbol of Taoist priests ordering ghosts and gods to obey their own orders during ceremonies, means that they can summon the corresponding heavenly generals to the altar to wait for their own orders, put down their tokens and beat the desktop, which means giving orders to ghosts and gods. It can be seen from this passage that the Taoist respect for tokens, even in peacetime, should be preserved respectfully.
