Mr. CHEN Liqun, former headmaster of Hangzhou Xuejun High School, started to be head of the Taijiang National Middle School, an ordinary school in Southeast Guizhou province, after his retirement 4 years ago. Over 1,000 students from the county school have become successful candidates for higher education through the national college entrance examination (2020). Encouraged by Mr. CHEN, close to 100 teachers from Hangzhou have offered long-term voluntary service in Taijiang.
