The National Wuhan University at the entrance of Wuda University was written by Cao Lian. The previous name of Wuhan University was "National Wuhan University" (1928). In the past, the writing order of Chinese was from right to left, so according to today's habit of going from left to right, it became "learning from great people and building the country by force", which was generous, meaningful and ingenious.

The wonderful coincidence of "learning from greatness" was first put forward by Professor Wu, vice president of Wuhan University, in 1950. There are generally two understandings about "learning from foreigners to control foreigners".

"Learn from a great man and build a country by force" means building a country by force like the Han Dynasty, which reminds people of the heroic declaration that "whoever makes me strong will be punished from afar". The other is to connect "Great Hanwu" and become "a country like Emperor Wu of the Han Dynasty". Needless to say, Emperor Wu of the Han Dynasty was a very talented emperor.
