May 31, 2012, SME sports class student leaders volunteered to clean up the small ads on the west side billboards of the main building in their spare time. In the morning, the student leaders firstly wet the small ads on the floor tiles or wall, then used steel balls or small shovels to carefully remove the small ads.
After everyone's efforts, the billboard took a new look. However, we found the cleaned place was quickly covered by new ads. This has to be a long-term effort to pursue. We believe with our joint efforts, Luantie graffiti advertising behavior will eventually be eliminated.
