Why did Koo always gargle in The Age of Awakening?

This is a reference to the behavior of the ancients.

Ku Hongming is a great adherent of traditional Chinese culture, so in terms of behavior, there are bound to be a lot of emulation of the ancients.

Traditional Chinese culture emphasizes the importance of "provenance" of poetry, words and even behavior, that is, every use of the dictionary, every iconic behavioral action, there must be a provenance, there is a counterpart of the previous generation. This kind of usage is a symbol of culture. Mr. Koo's gargling is in fact a "use of the dictionary".

The earliest allusion to Mr. Koo's gargling was not gargling, but washing his ears. Mr. Koo should have taken the ancient allusion to washing the ears, but in the Peking University meeting occasions, gargling is more convenient than washing the ears.
