NOTICE February 20th,2013 A heavy snowstorm destroyed a village last month. Many people are now sick because they don’t have warm houses to live in, not enough food to eat, and not thick clothes to wear. Also, the hospital was destroyed so they have to travel to other cities for medical help. However, the journey is very difficult and usually takes five or six hours. Next Saturday, students of No. 10 Middle School are going to give a performance. They will sing, dance and play music. The performance will start at 4 p.m. Each ticket will cost 20 Yuan and all the money will go to the people in the snowstorm-hit village. They will use the money to repair the hospital and their houses, and get them some food and clothes. Please join us! CA Charity
