What artistic techniques did Xiao Chuanjiu use to create the relief of Wuchang Uprising, a monument to the people's heroes?

The relief of Wuchang Uprising is a grand mass scene, with many figures and complicated structural relations. Grasping the overall structure and reasonable layout of the composition is the key. In order to reflect the warm fighting atmosphere in the limited frame, Xiao Chuanjiu skillfully uses multi-level processing to expand the space and give the characters ample room for action. In order to enhance the fighting atmosphere of the whole scene and perfectly embody the theme, he also increased the ups and downs of the figure to enrich the changes of light and shadow while keeping the relief large and concave. Because of the big ups and downs, there will be chaos and flowers. According to the needs of the picture, Xiao Chuanjiu made some ups and downs in some places, and some places were more peaceful, so that the main parts jumped, thus achieving the harmony between the combination of characters and the rhythm of composition.
