Through his efforts, Henan primary school, which had been closed for many years, resumed classes. Soon, Mr. Zhou Dejun founded Xiaohula Primary School.

In order to develop ethnic education, the Party and the government sent groups of educated and ambitious young teachers from the mainland to the border areas to set up schools, took root in the hard Hani villages and devoted their youth to ethnic education, which won the love of the Hani people and built an unforgettable monument in people's hearts. Zhou Dejun, Zhou Qiongfen, Xie Ya 'an, Zhou, Dao Yong Guang, Yang Xing, Liu Gang,,, Yang Dexian, etc. , are model and excellent teachers in frontier teachers, and pioneers and witnesses of primary and secondary education in Gelanghe Township.
