Professor Liao often refers to a row of trees on campus as subject for class. Two of them were not cared for fully after being transplanted as saplings. Their bark became cracked, and as a result they grew stunted and misshapen, in stark contrast to the trees around them.
廖日京常拿我們位在台大校園內的一排弟兄為上課教材，其中有兩棵因為苗木移植後缺乏照顧，皮開肉綻、長的畸型怪狀，和兩邊的樹比起來，一看就知發育不良，也影響整排樹的觀瞻。
