Not "Shen Xing", not Kang Youwei. Shen Xing moved because he faked his own death in prison, so he went to study in Japan after he got out of prison. Since then, he changed his name in Japan and was called Mr. Kang by people around him. This is actually understandable, because he changed his name to be safer and more convenient for him to engage in reform activities without causing trouble to people around him. It is reported that his pseudonym is Kang Wenzhuo, not the famous Mr. Kang Youwei in history. Therefore, Shen Xing is actually very smart, but he was not a very stable person when he was young. It was not until he met Zhou Ying that his character gradually stabilized from a dude. Later, he saved Zhou Ying.
