After the typhoon "Mangosteen" transiting, the trees nearby the Experimental Building and the Wen's building fell down, and the branches and leaves were everywhere. The overall sanitation was poor and obstructed the normal passage. In order to restore the beautiful campus environment and prepare for the resumption of work after the typhoon, on the afternoon of the September 17th, some teachers and student cadres from the College Office and the Experimental Teaching Center conducted a thorough rectification and cleanup of the environment around the building.
