What does the Riverside Scene on Qingming Festival mean?

The real intention of The Riverside Scene at Qingming Festival is the invasion of foreign enemies in the Northern Song Dynasty. As a traitor, Cai Jing took control of the imperial court. The painter Zhang Zeduan saw the social unrest at that time. In order to express to the emperor, he painted such a work. The real significance of becoming a Chinese painting lies in that it shows the prosperity of the market, but it is actually full of crises. There are vendors, vendors, restaurants, teahouses and passing carriages in the painting. In fact, these people are masterpieces sent by foreign enemies, and those who open teahouses are masterpieces. That is to say, the mountains and rivers in the Northern Song Dynasty are in jeopardy, and the emperor Lao Er still doesn't know it. Cai Jing, the eunuch, also controlled the imperial court, so Zhang Zeduan, the painter, drew this stunning painting to remind the emperor in order to make him understand. This is also the essence of Chinese painting.
