Chiang Kai-shek wanted him to go to Taiwan Province Province and didn't want to be wooed by the * * * production party. Chiang Kai-shek once used Du, and then ignored him. Du also realized that he was just Chiang Kai-shek's "urinal" and put it under the bed after use. He has lost trust in Chiang Kai-shek, so he went to Hong Kong.
