Hydro Power Station remained the country's largest until the 1980s - but the reservoirs they created in narrow, but fertile valleys of the Yellow River and its tributaries displaced a large number of local farmers. The three reservoirs flooded 118,229 (7,881 hectares) of farmland and displaced 43,829 residents, primarily in Yongjing County. The compensation payments to the farmers affected by the Yanguoxia and Liujiaxia Dams averaged, supposedly, 250 yuan and 364 yuan per person, were grossly insufficient to allow them to reestablish their way of life. It is said that the residents received lower compensation amount than they could otherwise because in 1958, when the Yanguoxia project started, they understated the value of their assets, as they were afraid to be classified as "rich peasants", i.e. class enemies. Even the more generous payments (averaging 1,100 per person) to those affected by the Bapanxia Dam were not an adequate substitute for the loss of the farmland. Traditional local products Linxia is famous for a certain style of round glasses worn during the Qing Dynasty that are still made there today. Food A type of thick cold wheat noodles called Niangpi (a species of Liangpi) is a popular local dish, served with spongy tofu and spicy sauce. Administration The CCP established the Linxia Hui Autonomous Prefecture in 1956 out of seven counties including Linxia City (Hezhou). In accordance with the 1954 PRC Constitution, autonomous prefectures were empowered to enact legislation in light of local circumstances. Theoretically, this would modify national law to accord with Shariah in case of the Hui ethnicity. However, in the nearly sixty years of Party-State rule (2010s), only seven local regulations have been passed pursuant to the power of legal autonomy. The only regulations that address Sharia (without naming it) are: The Measures on Linxia Hui Autonomous Prefecture Halal Food Administration. The Linxia Hui Autonomous Prefecture Religious Affairs Administrative Measures regulating mosques, mosque property, and mosque communities without reference to their Sharia equivalents (e.g., mosque property as Awqaf or pious endowments). The prefecture is subdivided into 8 county-level divisions: 1 county-level city, 5 counties and 2 autonomous counties: Demographics 2008 population was 2 million people. 2010 census counted 1,946,677. 2020-11 Census increased to 2,437,000.
