Ma Rusong shows the triangle ruler that he has used throughout his teaching career at home in Shenyang Village of Taizhou City, east China's Jiangsu Province, July 30, 2024bingocc. Ma Rusong, 84, used to be a teacher at Dalun junior high school in Taizhou. He returned to his hometown Shenyang Village in the city upon retirement in 2001. In view of the many left-behind children in the village, he decided to offer free tutoring sessions for those children at his residence.

He held tutoring sessions in mathematics, physics and chemistry on weekends and school vacations, and also took care of the children's mental health. Thousands of students have benefited from Ma's noble actions over the past two decades.

Ma said he himself used to be an orphan, and he would not be able to become a teacher without social support. He wanted to reciprocate whenever his service is in need. (Xinhua/Li Bo)
