System is a series of oil paintings that He made during the COVID-19 epidemic.

This work involves two independent elements: the part and the whole, that is, the part is essential for the unity of the whole. In nature, a small plant can be divided into various particles. The value of each individual part creates the value of complete nature. The whole will be complete and significant if the individual parts can be separated independently. Within these paintings there is a complex linear structure which implies an invisible system that influences and decentralizes the life of human beings.
