Almost 85 percent of Chinese people share just 100 surnames, with Wang, which literally means "king", being the most popular, the Xinhua news agency said on Tuesday. There are 93 million Wangs in China, followed closely by 92 million people with the family name Li and 88 million called Zhang, Xinhua said, citing newly-announced calculations by the Ministry of Public Security. Another seven common names -- including Chen, Zhou and Lin -- have at last 20 million members each, it added. Chinese family names can be traced back thousands of years and people generally feel a closeness to those with the same surname. But there are also some family names which are only used by a very few people, such as Guo, meaning to "cross over", and Mu, which means "mother".

BEIJING -- China may entirely switch to non-food materials such as cassva, sweet potato, sorgo and cellulose in producing ethanol fuel as a substitute for petroleum, said a government official. The country would approve no projects designed to produce ethanol fuel with food from now on, an official of the National Development and Reform Commission (NDRC) told a seminar on China's fuel ethanol development held in Beijing on Saturday. "Food-based ethanol fuel will not be the direction for China," said Xu Dingming, vice director of the Office of the National Energy Leading Group, who was also at the seminar. China has been trying to avoid occupation of arable land, consumption of large amount of grain and damages to the environment in developing the renewable energies. The current four enterprises engaged in producing corn-based ethanol would be asked to switch to non-food materials gradually, according to the NDRC official who declined to be named. The four enterprises in Jilin, Heilongjiang, Henan and Anhui have a combined production capacity of 1.02 million tons of corn-based ethanol per year. The country has become a big producer and consumer of ethanol fuel in the world after the United States, Brazil and European Union, according to the NDRC official. China Oil and Food Corporation (COFCO), the country's largest oil and food importer and exporter, would focus on sorgo in the production of non-food-based ethanol fuel, said Yu Xubo, president of COFCO at the seminar. COFCO, which owns the Heilongjiang enterprise and has a twenty-percent stake in the Anhui enterprise, aims to produce five million tons of ethanol fuel based on sorgo in the near future. COFCO is leading the way in developing cellulosic ethanol fuel under a cooperation agreement with Denmark-based Novozymes, which leads the world in researches into the key enzymes needed in large-scale production of cellulosic ethanol. The current cost for producing ethanol fuel from stalks of corn, which are discarded by farmers, is still too high. Novozymes is working on the commercialization of cellulosic ethanol both in the United States and China. "We are optimistic about China's prospect of making it work ahead of the US, as the cost of collecting the stalks of corn are much cheaper in China," said Steen Riisgaard, president and CEO of Novozymes. There is much opposition both in China and in the world to corn-based ethanol fuel, which is believed will lead to higher corn price.

Central China's Hubei Province has banned pearl farming in all lakes, rivers and reservoirs in an attempt to prevent water quality from worsening, local aquatic products administration said Saturday.Pearl farms have covered a total area of 13,000 hectares in the province, and the annual output has exceeded 400 tons, a spokesman with the administration said.Some farmers resorted to pesticides and manure to farm the pearl oysters, which has caused swathes of algae to bloom in the water, and turned the water stinky, he said.The administration said it would not approve new applications to establish such farms, and has ordered all water areas used to cultivate pearls to be cleaned.Over the past several months, blue-green algae outbreaks, usually caused by pesticides runoffs and other pollutants, have been reported in Taihu Lake, Chaohu Lake and the Dianchi Lake in southwestern China, endangering domestic water supplies.Zhou Shengxian, director of the State Environmental Protection Administration (SEPA), unveiled a set of tough new rules early July to tackle worsening pollution in the three lakes.The rules include a ban on all projects involving discharges containing ammonia and phosphorus. He also ordered all fish farms to be removed from the three lake areas by the end of 2008.

The country's campaign to improve product quality and food safety has yielded very good results, Vice-Premier Wu Yi said in Weifang, Shandong Province, October 26, 2007. [Newsphoto]Weifang - The country's campaign to improve product quality and food safety has yielded very good results, Vice-Premier Wu Yi said on Friday.Despite that she urged: "We have to win this special war against poor product quality and supervision, enabling our people to eat without fear."Wu said the government has raised its investment in agriculture, especially in pesticide supervision and fertilizers management and to prevent fake products from entering the sector.Besides, authorities will strengthen supervision and inspection on vegetables and other food products in major cities, bringing all wholesale markets within the authorities' monitoring system.Officials are already monitoring all wholesale markets for agricultural products in 676 medium- and large-sized cities, Minister of Agriculture Sun Zhengcai said.Latest data suggest 94 percent vegetables and 95 percent aquatic products in cities have pesticide residue below the danger level.Also, more than 97.4 per cent of the pigs are slaughtered in registered abattoirs. The authorities closed down 602 illegal and 4,051 slaughterhouses in the first half of this year alone.Concerns over Chinese products safety prompted the government to formed a cabinet-level panel on food safety and quality control under the vice-premier in August.Eight categories of products are under the panel's scanner, including pork, drugs, agricultural products, processed food, toys and electric wires. The "special war" is aimed at improving product quality in four months.At a meeting in Weifang, Shandong Province, Wu lauded the province's advanced practice in product quality and food security management."Shandong's experience in standardized plantation of vegetables, aquatic products and some other agricultural products has been proved effective and worth promoting nationwide," Wu said.It brings irrigation and the condition of cultivable areas, particularly where chemicals are used, under a quality control system, which will be overseen by local officials, Shandong Governor Jiang Daming said.The province has taken the lead in the country to set up internationally recognized systems of quality standards, quality testing, attestation and supervision, securing a high standard of food quality from every link of production, processing and transportation.And more than 400,000 people in the province have attended into food safety education training sessions since August.
