“Encircling the city”is a group of works composed of Qin bricks and images of the ancients. In the creation, thin fetal porcelain clay is used for manual molding. After firing with high-temperature reduction flame, the full picture of the work is presented through comprehensive material gypsum. My thinking is not the siege set by the environment, nor the pressure imposed by others, but that we imprison ourselves. In real life, in order to realize the ideal self, we should let ourselves degenerate and grow instead of complacency.
