Spring is abundant and the sun is warm. On the hillside behind the plum garden on the campus of Jiangsu University, a gorgeous sea of colored rapeseed flowers is blooming in the wind, attracting many teachers, students and tourists to come to enjoy and take photos, and becoming a feature of the campus. In the colorful sea of rape flowers, a touch of "voluntary red" has become a different kind of scenery. The School of Life Sciences of Jiangsu University organized a special student volunteer service team to provide students, teachers and tourists with popular science explanation, photo guidance and other intimate services.
