格言大意：知道就是知道，不知道就是不知道，这才是明智的态度。

Main Idea: It is wise to admit openly what you know and what you don’t know.

不懂就问（Asking when you not understanding）

    有一次，孔子到鲁国的太庙，看到有很多自己不明白的地方，便不厌其烦地向别人请教。有人看见了，便笑话孔子，说他那么大的学问，到了这里还什么都问，对此，孔子并不在意。
    Once, Confucius went to the Imperial Ancestral Temple of Lu and saw many things he didn’t understand. So he consulted others, not minding to take all the trouble. Some people laughed at Confucius when they saw this. They said that he asked about everything when he came here though he was a man of great learning. Confucius didn’t mind at all.
