A two-day voluntary graffiti event kicked off on April 16 at the Hongjialou Campus of Shandong University's (SDU) Fine Arts School for the approaching World Earth Day, which is on April 22.

Themed on environmental protection, battling the COVID-19 epidemic, and traditional culture, volunteers drew fine graffiti on well lids, trees, and cracked brick floors.

The graffiti decorations have brought vitality to the campus and have become the hot spots for teachers and students of the school to take photos.

The graffiti event not only decorated the campus, but also enriched campus culture.
