Tsai Chung-han points out that the style of the Japanese professors is to look first at the references in a thesis; if something isn't there they think should be, they think you have a gap. They even consider punctuation: if that isn't done right, the thesis likely isn't done right either.
蔡中涵也指出，日本教授的作風是：看論文先看參考書目，若是他覺得這個研究有些書該列未列，就認為你有所疏漏；教授們甚至認為，如果連標點符號這種細節都弄不好，論文是不會好的。
