It is a god-sister relationship. However, some people have suggested that Yoshiko Kawashima is Li Xianglan. This view has attracted people's attention since it was introduced, but according to history, Li Xianglan and Kawashima Yoshiko are not the same person. Because in the same situation, two people are doing different things. If it is one person, it will be exhausted! After the founding of the People's Republic of China, there were widespread rumors in China that Yoshiko Kawashima had been killed. However, some people say that Kawashima Yoshiko is not dead and that it is just a fake corpse. But no matter what, the rumor that Yoshiko Kawashima is Li Xianglan is not credible. Li Xianglan admitted more than once that Kawashima Yoshiko was his god-sister, but at that time Kawashima Yoshiko was a spy, often wore military uniforms, and was a bit masculine. So Li Xianglan often calls him brother.
