Puyi finally decided to expel all of the eunuchs from the Forbidden City to end the problem of theft, only agreeing to keep 50 after the Dowager Consorts complained that they could not function without them. Puyi turned the grounds where the Hall of Supreme Harmony had once stood into a tennis court, as he and Wanrong loved to play. Wanrong's brother Rong Qi recalled: "But after the eunuchs went, many of the palaces inside the Forbidden City were closed down, and the place took on a desolate, abandoned air." After the Great Kantō earthquake on 1 September 1923 destroyed the cities of Tokyo and Yokohama, Puyi donated jade antiques worth some £33,000 to pay for disaster relief, which led a delegation of Japanese diplomats to visit the Forbidden City to express their thanks. In their report about the visit, the diplomats noted that Puyi was highly vain and malleable, and could be used by Japan, which marked the beginning of Japanese interest in Puyi.
