The idea was to show the dean how they would never consider taking an object that wasn't theirs. The dean, however, thought that since these pieces of clothing all bore name tags, it would make more sense just to take them to their owners. Then the students starting pulling the name tags off the clothing they found.
訓導人員認為衣服上有名牌，送回去就好了，為了加分，學生後來再「撿」到衣服就先把名牌撕掉，以便符合拾物不昧的條件。
