How to paste the door god correctly?

The doorkeeper is regarded as "on duty at once", the first one, eliminating disasters and increasing happiness. Second, the doorman should stick it on the outermost door of the house. Generally speaking, double doors with the same width should be attached to one side. If the door is open on one side or the side is small, the door keeper can only stick to the door on one side, leaving a certain distance between the left and right.

Door-keeper, that is, the guard of Simen, is a painting posted on the door during the Lunar New Year. As guardians of folk beliefs, people stick idols on doors to drive away evil spirits and ghosts, defend their homes, maintain peace, help public utilities and bring good luck. It is the beloved patron saint of China people. According to traditional customs, every household is busy writing couplets and door gods on the eve of the Spring Festival to pray for the coming year.
