conduct an aerial survey of the flood zone. Although Song Ziwen remained the head of the commission, the day-to-day running the relief effort was entrusted to John Hope Simpson, a British refugee expert. Charity poured in to help with the relief effort from throughout the world, with overseas Chinese communities in Southeast Asia being particularly generous. In the United States, the celebrated author Pearl Buck wrote short stories to encourage charitable donations. The relief effort became much more difficult following the Japanese invasion of Manchuria in the autumn of 1931, which caused the Chinese bond market to collapse. Eventually, the government managed to secure a large loan of wheat and flour from the United States. In the wake of the disaster, the government set up organizations such as the Huai River Conservancy Commission to address flood problems. However, due to a lack of funding and the chaos of the Second Sino-Japanese War and the subsequent Chinese Civil War, the various commissions were only able to construct small dams along the Yangtze River. As part of an anti-superstition campaign by the Kuomintang Government, a Dragon King Temple was demolished in Wuhan shortly before the flood-hit. This coincidence led to widespread discontent afterwards, as many locals linked the disaster to the anger of Dragon King, a rainmaking deity. As a response, prominent officials, including He Baohua, mayor of Wuhan, and Xia Douyin, then the local garrison commander and later governor of Hubei Province, held ritual ceremonies and kowtowed to the deity. Meanwhile, many believed that evacuation efforts were hindered by superstition. According to a contemporary report, thousands "are convinced that Hankow is doomed and refuse to help themselves or be helped. They sit stoically awaiting death." Communist Era (1949–present) In 1953, after the end of the Chinese Civil War, Chinese Communist Party leader Mao Zedong travelled to areas neighbouring the Yangtze River to promote the Three Gorges Dam flood control project. "The Socialist Three Gorges Dam project should excel other major projects in Chinese history such as Qin Shi Huang's Great Wall and Sui Yang Di's Grand Canal", he stated. Scientists and officials who raised doubts, such as Chen Mingshu, were persecuted as rightists. Li Siguang, a prominent scientist and minister of geological resources, told Mao he would commit suicide if he could not stop the construction of the dam. The project did not move beyond the planning stage in Mao's time,
