Oxfam Hong Kong provided water in Yunnan. A major fundraiser was also held that raised 280 million yuan. Many celebrities took part including Wang Feng, Elva Hsiao, Andy Lau, He Jie, Jackie Chan, , Yan Weiwen, Zhou Xiao'ou (), Bibi Zhou, and Yang Zi. The Hong Kong government also approved a HK$1.4 million grant. Many donations of bottled water have also arrived in Guizhou and other parts of southwestern China from around the country. In mid-June 2010, a large algal bloom, consisting of "enteromorpha" algae, developed off the coast of Shandong, in the Yellow Sea. Causes of the algal outbreak include marine pollution from sewage and agricultural run-off, in addition to run-off from fish farms, worsened by eutrophication following the drought, subsequent flooding and heat wave, as well as high sea surface temperatures in the area. The bloom continues to expand, and preparations have been made for a flotilla of vessels to ward off the bloom, covering an area of , the largest bloom since 2008. The patch of algae since expanded offshore Jiangsu Province, and is pushing toward the city of Qingdao. The Chinese State Oceanic Administration has warned that the algae could threaten marine life and local tourism, and other scientists have stated that the bloom could decompose on beaches and release toxic gases if not cleaned up. Close to 4,000 tonnes a day of algae is being removed from the bloom, to be sent off and used as animal feed or fertilizer. Green and red tides have become more common in China in recent years. The green tides from the current algal blooms can also result in dead zones from localized ocean anoxia. Large blooms of jellyfish, including giant Nomura's jellyfish have also appeared off Shandong and around the coasts of Japan within the past decade, as a result of the same type of pollution in dead zones.
