A massive school re-building project is needed in the earthquake-devastated Bachu county in northwest China's Xinjiang Uygur Autonomous Region, according to officials there. About 900 classrooms were demolished in the quake on Monday which measured 6.8 on the Richter scale and also killed at least 260 people and injured more than 1,000. Officials are still working out the costs involved in rebuilding the schools and bringing in textbooks, teaching materials, desks, chairs and other needed supplies, said Leung Mei-mei, who is part of a four-member relief team from World Vision Hong Kong now in the county. She said officials there were hoping to have all classes running again this year. More than 100 students have just returned to classes in the former Kezihikemu elementary school, where soldiers have pitched six tents, according to Xinhua. About 100,000 homeless people are also being housed in tents. A priority for the government was to ensure basic food supplies for the victims, said Ms Leung. But getting children back to school as soon as possible was also important. 'A few of the children I talked to were still in shock from the disaster. Being back in school again can help them deal with the loss of family members and adjust better to future changes,' she said World Vision Hong Kong has committed a minimum of $200,000 towards building quake-resistant schools in the region.
