Compared with Xiamen, Ganzhou is not a hot tourist destination. But when it comes to earth buildings, it is familiar. Fujian's classic earth buildings are mainly distributed in Yongding County of Longyan City and Nanjing County of Cangzhou City. The famous earth buildings in Yongding County are concentrated in Hukeng Town and Xiayang Town. The famous earth buildings in Nanjing County are concentrated in Shuyang Town and Meilin Town. Nanjing County, the ancient name of Lanshui County, brings together the oldest, most beautiful, highest, largest, smallest and most unique earth buildings in the country. The Tulou Scenic Area is distributed in a circular shape with a diameter of 10Km. The most famous ones are Tianluokeng Tulou Group, Dongpu West Lean Yuchang Building, Hekeng Tulou Building, Huaiyuan Building, Hegui Building and Taxia Village. The name of the Tianluokeng Tulou Group originated in the 1960s. The satellite photos taken in the United States mistaken the five earthen buildings in Tianluokeng as China's nuclear reactors, causing the international community to be at a loss. In addition to the role of nuclear reactors and the World Heritage List, today's fame is also known as the "four dishes and one soup."
