Abstract
Qing Ming Shang He Tu, also known by its English name as the "Along the River during the Qingming Festival", is one of the most famous paintings in China to describe the human’s daily life in the capital city Bian Liang (also known as Dong Jing and Kai Feng city today) of Northern Song dynasty. It captures the environment and activities of the city and rural area on both banks of River Bain including architecture, street networks and arrangements, commercial trading activities, characters, transportation, etc. There is a lot of debates about the season described in the painting, most of which is attributed to the spring tomb sweeping festival, to reflect the two words "Qing Ming" in the name of the painting. However other scholars thought some scenes in the painting also show that this is not the scene appearing in the spring, so the season in the painting should be autumn. In addition to the studies in history and in the painting, this study, from a scientific perspective, reproduces the scene model in "Qing Ming Shang He Tu", through CFD, simulating the environmental conditions of spring and autumn, to discuss the mystery about the season in "Qing Ming Shang He Tu" by thermal comfort analysis method.
