The traditional custom of door gods' New Year pictures.

According to Han folk customs, New Year pictures can ward off evil spirits, pray for good luck and welcome auspicious events. In the process of praying for a bumper harvest, worshipping ancestors and exorcising evil spirits, the corresponding festival decoration art gradually appeared. At the beginning of the new year, the first thing is to put up the door. The ancients attached great importance to the portal, resulting in the worship of the door god. In ancient times, people had the custom of painting chickens and tigers on doors, hanging reed ropes and picking peach symbols. Later, samurai door gods and literary door gods emerged in large numbers. Until the Tang Dynasty, the images of Qin Qiong and Weichi Gong were widely pasted on the doors of Han people to ward off evil spirits, and they began to become real door gods. Door gods are the most important manifestation of New Year pictures. Early New Year pictures were all hand-painted, and they were pasted on the doors every Spring Festival, once a year, and different door gods were pasted on the doors of different rooms. Later, people began to print the door gods in the form of printmaking, and the door gods became more popular.
