Yucheng Primary School is located by the Qingyi River in Caoba Town and is a rural window school in Yucheng District. However, due to having only one piano, it is far from meeting the needs of music education and teaching. In October 2020, the Sichuan Tibet Charity Tour of the "Happy Qin Key" Music Classroom came to Ya'an to help improve the quality of music teaching and enhance the level of quality education in the school.
