Despite most students having no prior foundation in art — 80 percent of whom have never drawn under professional guidance — Wu believes they can reach the same level as students in Hangzhou.

"The children here are very imaginative. I hope that even after I leave, they will continue to find joy in painting," he said.

Sangzhu Lhamo, a shy 13-year-old sixth grader, is particularly fond of the art room. Her home is about 150 kilometers from the school, a four-hour drive away, so she spends most weekends at school.

"I really like going to the art room. Painting is a happy thing," she said.

"Previously, the school had no dedicated art teacher, and other teachers, who were not professionally trained but served as substitutes for art teachers, sometimes lacked confidence," Principal Mao said.

He plans to have those teachers learn art education from Wu so they can continue guiding students after he leaves.

"All students have one art class per week. I also support Wu's suggestion to let students manage the art room themselves," the principal said.

The principal further noted that students have expressed their fondness for Wu and their enjoyment of painting.

"Students told me they didn't know how to start drawing before. Wu has taught them not only how to appreciate art but also how to begin creating it," he added.

Wu's arrival in Garze is part of China's educational aid policy for the Xizang autonomous region and other Tibetan prefectures in the provinces of Sichuan, Gansu, Qinghai, and Yunnan, aiming to boost education quality and close gaps between Xizang and other parts of China.

The head of the Education Bureau of Shangcheng District, Xiang Haigang, said they have sent their best teachers for educational support.

"I have never considered art education as a secondary subject. In the journey toward modernizing education in China, art, sports, and labor education are all extremely important. Deploying our outstanding teachers to relatively underdeveloped areas brings significant improvements and meets fundamental needs for comprehensive development," he said.

In developing areas, there is often a shortage of teachers for so-called secondary subjects. Such education allows children to experience and discover beauty, helping them understand what constitutes a good life in the future, which is crucial in the educational process, he said.

He also believes that art teachers can help Tibetan students better record and pass on their ethnic culture through art. "Additionally, it helps children recognize that Tibetan culture is also a part of Chinese culture," he said.

Xiong Bingqi, director of the 21st Century Education Research Institute, noted that art education is lacking in underdeveloped areas in China, with a shortage of teachers and insufficient attention from local governments.

Having teachers provide support in these areas is beneficial, but the extent of its effectiveness depends on how the teachers approach their work, Xiong said.
