What are the same inspirations of Mei Lanfang's growing a beard and Cheng's refusing to act?

We must have firm national integrity and deep patriotic feelings. Mei Lanfang's Beard is a self-reading text, which tells a touching story in the life of the famous Peking Opera artist Mei Lanfang. During her stay in War of Resistance against Japanese Aggression, Mei Lanfang first moved to Hong Kong, then grew a beard, realized her ambition, and even took the initiative to find a "disease". Mei Lanfang's beard growing and Cheng's refusal to perform have the same enlightenment, that is, firm national integrity and deep patriotism. All kinds of behaviors fully show his strong patriotic thought and lofty national integrity.
