Passengers head home at a railway station in Xi'an, Shaanxi province, on a smoggy day, Jan 17, 2017. [Photo/IC] To cope with the smog that has plagued North China for years, one man has come up with an innovative idea that might go beyond your imagination. Du Honglai, a resident of Beijing, has applied for a national patent for his idea, which proposes the mobilization of all the city's residents to fan away the smog, according to a report from the Legal Daily. Du said the approach requires 15 million people to wave a fan at the same time in the same direction, which can produce powerful winds. He said the new approach not only is low cost and effective, but also generates no secondary air pollution. According to his calculations, if 15 million people wave fans at the same time in the same direction for an hour, the air that occupies a space 40 meters high, 20 kilometers long and 20 km wide (roughly the area of downtown Beijing) will be expelled 68 km away. Du calls for government agencies to offer a fan to all able-bodied people in the city to expel the smog during breaks from class and work, according to a report of thepaper.cn. In his application, Du has also designed fans in a variety of sizes that fit people of different ages and physical conditions. But the man did not reveal whether he has done any experiments on his idea. The patent application Du submitted in March has not yet been approved for substantive examination by the State Intellectual Property Office. The website of the SIPO shows that Du has also applied for patents for his inventions including a timed mosquito killer and nose plug for swimming. In 2016, Beijing's density of PM2.5, hazardous airborne particles measuring 2.5 microns or less in diameter, was 74 milligrams per cubic meter, double the health maximum of 35 mg per cubic meter set by the government. personalised rubber wristbands24 hour wristbands202mm to inchescustom fidget
WANG WENJIN/CHINA NEWS SERVICE More than 80 people with the surname Zhang traveled from Taiwan to Xiamen, Fujian, in August to discover their roots. People are studying their family trees and age-old stories in the hope of reconnecting with long-lost relatives. Zhang Yi reports from Xiamen, Fujian. On June 9, Huang Ching-hsiung woke at about 3 am in his hotel bed in Xiamen, Fujian province. He was too excited to sleep. At daybreak, he was one of a group of 11 members of his family that set out to visit Pujin, a village two hours from downtown Xiamen by road. The settlement has the same name as Huang's home village in Lugang town, Changhua, Taiwan, and most of the residents are named Huang. The Huangs on Taiwan are direct descendents of settlers who arrived on the island centuries ago. Several batches of Fujian residents moved to Taiwan during the Ming Dynasty (1368-1644) in the hope of making their fortunes, and those who were members of the same family banded together as they fought to make new lives. They named the places they settled after their hometowns and retained the customs they had brought from the mainland. Roughly 80 percent of Taiwan residents share blood ties with people from Fujian. About 110 settlements on either side of the Taiwan Straits that share the same village and family names have established official exchange programs, according to the Fujian-Taiwan Compatriots' Association. In the 1980s, the descendants of those early settlers started visiting the mainland to discover their roots, inspired by family histories passed down through generations. Place your feet on the land our ancestors came from, Huang's father told him, shortly before he died 12 years ago.
