What is the origin and development of the door god painting with Zhong Kui as the theme?

In the Tang Dynasty, children's paintings with Zhong Kui as the theme began to appear. Yi Shi in the Tang Dynasty recorded that Emperor Ming of Tang Dynasty was lying in the daytime due to illness, dreaming that the blue robe was a ghost to catch a kid, claiming to be a scholar in Zhong Nanshan, and vowing to eliminate evil for the world. Ming Taizu woke up from a dream and recovered. It's a letter to Wu Daozi, "to drive away evil spirits and calm down evil spirits". In the New Year, it became the practice of the Tang Dynasty to reward ministers with Zhong Kui's paintings. This is the custom that people hang Zhong Kui in the house to exorcise ghosts, put a door god on the door to ward off evil spirits, and set a peach symbol beside the door. For example, in the Qing Dynasty, Zhu Mo in Fengxiang, Shaanxi Province printed Zhong Kui. After the Tang and Song Dynasties, the main image of the goalkeeper gradually evolved into two generals, Qin Qiong and Jingde. Woodblock New Year pictures are distributed all over the country. Qin Qiong's and Jingdezhen's paintings of door gods have continued this style, and almost all of them have images such as "whip", "whip off", "hammer standing" and "axe standing", such as the door gods in Xiaoli Village, Fengxiang County, Shaanxi Province.
