Among Chinese myopia patients,30million are severe patients, according to ZhouThe prevalence of myopia among high school and college students is more than 70 percent,and the situation is continuously worsening, he Zhu, director with the China Youth Development Service Center, said long hours ofstudy, lack of exercise, especially outdoor activities, and attachment to electronic screen aresome of the top reasons behind the widespread myopia problems, and the increase ofyounger patients, although China has made great progress in improving the hardwarefacilities and lighting conditions in said he hopes the survey will alert people on the threatening situation, and also helpmedical experts to better guideline parents and children39。ll hold off jogging for a while.

She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 years, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to bee pregnant. I conducted prehensive physical checkups. The results suggested that Xiao39。s Guangzhou city anized the Chengdu festival. A terrifying wooden bridge in China has just been replaced by a glass one. This, the world’s longest glassbottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground. The floor is made of doublelayered glass that is 24mm (), and is reportedly 25 times stronger than regular window glass. The bridge had previously been made of wood, linking the two peaks of Stone Buddha Mountain, but 11 engineers working 12 hours a day converted it to glass. Previously, you were considered brave if you steeled yourself to cross the wooden walkway。s most popular dishes are his brainchild. Lin says his secret of success is innovation rooted in experience: He spends months every year traveling and eating worldwide, seeking new ingredients and inspirations that could improve the offerings of Blue Frog restaurants. The restaurant chain regularly launches a new seasonal menu, usually featuring eight new dishes with fresh ingredients. The bestselling seasonal dishes later replace the least popular items on the regular menu, which is usually updated in late fall and boasts a selection of about 40 dishes. Food should have no boundaries, Lin says. As long as the food tastes good and is healthy, it doesn39。s juicy, tender texture and its delicious beef flavor. Matching that Sichuan flavor with cheese created a new taste experience.
