Lu Xun visited Hong Kong in 1927 for two days and gave two very important lectures, but for several decades little was known about who made the invitation and who organized the trip. In 1981 Liu Sui claimed that it was Dr. Wong San-yin who invited Lu Xun, and Liu Sui himself was part of a reception team headed by Dr. Wong. In 1993 Zhao Jinsheng revealed that he was the person who had invited Lu Xun and organized his trip and lectures. Recently materials supporting both claims have been discovered and this paper examines these two claims, concluding that Zhao Jinsheng’s account is more reliable.
