After graduating from normal education major in 2013, Tu worked as an assistant in a training institution and did community work, but she always dreamed of being a teacher. In 2016, she passed the teacher recruitment examination of Jiangxi Province and became a rural teacher. In the past three years, Tu Youyou has won the recognition of her students' parents. Now, the 29-year-old rural teacher is the principal of Shangban primary school. In the school, most of students are left-behind children. Tu Youyou found that many of them were interested in music, dance, painting and sports. To enrich children's life, she invited voluntary teachers in 2018 to set up various courses, including dance, piano, taekwondo and tennis, and studied piano on her own for teaching. Students call her "sister principal" and are willing to share their stories with her. (Xinhua/Peng Zhaozhi)
