What is the relationship between Chuan Dao Yoshiko and Li Xianglan?

This is sisterhood. However, some people think that Yoshiko Kawashima is Li Xianglan. This view has been concerned since it was put forward, but according to historical records, Li Xianglan and Kawashima Yoshiko are not the same person. Because at the same time, two people are doing different things. If they are alone, they must not be exhausted! After the founding of People's Republic of China (PRC), it was widely rumored in China that Chuan Dao Yoshiko was killed. However, some people say that Kawashima Yoshiko is not dead, but a fake body. But in any case, the rumor that Kawashima Yoshiko is Li Xianglan is not credible. Li Xianglan has admitted that Kawashima Yoshiko is his godsister more than once, but at that time, Kawashima Yoshiko was a spy, often dressed in military uniform, and a little manly. So Li Xianglan often calls him brother.
