Some time after the events of the Battle for Yu Dao, the professor was asked by Earth King Kuei to give a lecture in Yu Dao on ancient theories of government, in the hopes they could be used to "build a society of the future". In attendance at his lecture, among a number of other dignitaries, were AvatarAang, Katara, Sokka, and Fire LordZuko, all of whom, with the exception of Katara, showed little interest in what the professor was saying. However, his mention of the word "family" peaked Zuko's interest, and upon the Fire Lord's request, the professor reiterated an ancient Earth Kingdom philosophy regarding the nature of family and government, and how the two are invariably intertwined. Upon finishing his statement, he returned to delivering his lecture with the same monotony as before.
The professor's design is based on Confucius's traditional appearance; the philosophy the professor was explaining, regarding the connection between ruling a family and governing a state, is loosely based on Confucian philosophy.
