This painting depicts the bustling scene and natural scenery on both sides of Bianliang and Bianhe, the capital of the Northern Song Dynasty, during the Qingming period. In the form of long scrolls, the composition method of scattered perspective is adopted to bring complicated scenery into a unified and changeable picture. There are more than 1000 people in the painting, with different clothes and expressions, interspersed with various activities, paying attention to drama, dense composition, rhythm and rhythm changes, and ingenious brushwork. The whole picture is divided into three sections. In the first paragraph, the spring scenery in Bianjing village: in the sparse forest mist, several huts, grass bridges, running water, old trees and boats, two porters are driving five donkeys carrying charcoal to the city. A willow forest, with faint green branches, makes people feel that although it is chilly in spring, it is already spring back to the earth. In the sedan chair on the road, a woman sat in it. The top of the sedan chair is decorated with willows and flowers, followed by riders and bearers, returning from a walk in the suburbs of Beijing to sweep the grave. The description of the environment and characters points out the specific time and customs of Tomb-Sweeping Day, which opens the curtain for the whole painting. In the middle section, the busy Bianhe Wharf: Bianhe is the national water transportation hub and commercial traffic artery in the Northern Song Dynasty. As can be seen from the picture, the crowd is dense, food ships are gathering, some people are resting in the teahouse, some are reading fortune-telling, and some are eating in the restaurant. There is also the "Wang's Paper Horse Shop", which is a grave sweeper selling sacrifices. Ships in the river come and go, end to end, either pulled by trackers or paddled by boatmen. Some are full of goods, going upstream, and some are nervously berthing to unload. Across the Bianhe River is a large wooden arch bridge with exquisite structure and beautiful shape. Such as flying rainbow, hence the name Hongqiao. There is a big ship waiting to cross the bridge. The boatman is supported by bamboo poles; Hook the bridge with a long pole; Lead the boat with hemp rope; Several people are busy lowering the mast so that the ship can pass. People in the neighboring ship are also pointing, as if shouting something. Both inside and outside the ship are busy crossing the bridge for this ship. People on the bridge are also sweating over the tense ferry scene. This is the well-known Hongqiao pier, which is full of traffic and bustling, and is really the intersection of land and water transportation. In the second half, the bustling urban streets: centered on the tall towers, there are rows of houses on both sides, including teahouses, restaurants, foot shops, meat shops, temples, public halls and so on. Silk, jewelry, spices, incense, paper horses and so on all have specialized businesses. In addition, there are medical clinics, car repair, fortune telling, shaving and plastic surgery, and all walks of life have everything. Large-scale shops are also tied up with "colorful buildings and happy doors", and banners are hung to attract business, and pedestrians in the market are jostling with each other. There are businessmen who do business and people who look at street scenes. There are monks walking around with baskets on their backs, tourists asking for directions from other places, street children who have heard of books, children of rich people who drink heavily in restaurants, disabled elderly people begging on the edge of cities, men, women and children, scholars, farmers, workers and businessmen, and so on.

Artistic Features From The Riverside Scene at Qingming Festival, we can see several very distinctive artistic features: First, it is rich in content. The Riverside Scene at Qingming Festival adopts the method of constantly moving the viewpoint, that is, "scattered perspective" to capture the required scene. From the vast Yuan Ye, the vast rivers, the towering battlements, to the nails and rivets on ships and cars, the small commodities on vendors, and the words on the market, they are all harmoniously organized into a unified whole. There are officials, farmers, businessmen, doctors, monks, Taoist priests, petty officials, women, children, teachers, laborers and so on, as well as donkeys and horses. There are fairs, trading, hanging out, drinking, parties, pushing boats, pulling carts, riding cars, riding horses and so on. There are many shops, hotels, teahouses and dim sum shops in the street, as well as towers, river ports, bridges, cargo ships, government buildings and thatched cottages. There are 1695 people, more than 60 kinds of livestock, more than 20 wooden boats, more than 30 pavilions, and more than 20 sedan chairs. Such rich and colorful contents are rare in ancient paintings of past dynasties. People of all colors engage in various activities, not only with different clothes and facial expressions, but also with various activities, full of dramatic plot conflicts, which make viewers look at the industry with endless aftertaste. Second, the structure is rigorous, complicated but not chaotic, long but not redundant, and the paragraphs are clear. What is commendable is that such rich and colorful content, prominent theme, echo from beginning to end, the whole volume is seamless. Every figure, scene and detail in the painting are arranged reasonably, and the relationship between the pictures, such as density, simplicity, movement, gathering and dispersion, is handled properly, so as to be complex but not miscellaneous, but not chaotic. It fully shows the painter's profound insight into social life and superb ability to organize and control pictures. Thirdly, in terms of techniques, the combination of big brushwork and meticulous brushwork is good at choosing vivid and poetic things, scenes and plots with essential characteristics to express. Observe life very carefully and portray every character and prop. Everyone has his own identity, way and plot. Buildings, bridges and other buildings are rigorous in structure and detailed in description. Cars, horses and boats cover everything, so we should be small without losing the whole picture and its potential. For example, the objects on the ship, the way of nailing and riveting, and even the method of tying the rope are all explained clearly and magically.
