Jincheng Seventh Primary School was originally a rural primary school in Jincheng Town, Jinning County, Kunming City, with students mostly from surrounding towns. In August 2020, Lang Lang donated a music classroom on behalf of the Spring outing family to Jincheng No.7 Primary School in the second season of the variety show "Youth Journey", allowing it to accompany the children's happy growth and leave behind beautiful memories shared by the Spring outing family.
