For someone who changed sides at the very last minute, it was only right to show some sincerity. Otherwise, who would know whether the same situation would happen all over again?
This was like a funny online article titled, "The Biography of an Early-Slow Bear" that Sui Xiong recalled reading some time back. The biography was about a man termed as an Early-Slow Bear, who, from the end of the Ming Dynasty to the beginning of the Qing Dynasty, had changed sides countless times. He had no moral integrity to speak of, and seriously speaking, he had no base limit to how despicable he could be, even as a human being himself. Back then, out of curiosity, he once asked, "Was the situation really that chaotic back during the end of the Ming Dynasty? Should I just surrender and change sides?"
