Principal Zhang Juncheng was born in a poor family, and his living conditions were not very good since he was a child. All the clothes he wears are left by his brothers, and none of them are new. There are many patches on it, and his shoes show his toes. Sometimes when he encounters difficulties at home, he basically has a meal at home. In order to reduce the burden on his family, he did not continue his studies after graduating from junior high school and went to the society. When he works, he goes to work.
As a security guard in Peking University, Zhang Juncheng works very hard these days. He bought some English books himself. I often read all night because I don't have time to read when I stand guard during the day. Sometimes, in order to have more study time, he took the initiative to sign up for a midnight class and almost squeezed out all the time to read books and brush questions. Besides standing guard, he is studying. What a strong will it takes to persist. Over time, many teachers and students of Peking University knew about his security experience. Later, he successfully obtained the graduation certificate of law major from Peking University.
