In 2002, Li Ding graduated from Normal University. In that year, there was also the saying that he was assigned to teach in a rural middle school after coming out of the mountain valley. He took a nearly three-hour drive from the city to arrive at the place where he was about to teach. Hexing Middle School is the only junior middle school in Hexing Township. After the students graduated, the high school needs to go to the county. The school is not very big, with only more than 300 students in total, and there are eighteen teachers. In recent years, there have been no new teachers assigned to the editorial school. The school leaders have been to the county’s education committee several times and finally brought a newly graduated college student. Although Li Ding studied in a third-rate normal school that is not even a provincial key, it is already the highest-level education in this aging middle school that is generally over 40 years old.
