Dear Daming,
I'm sorry to hear that a big earthquake happened in Ya'an, Sichuan. Some school buildings broke down in the earthquake and many students couldn't go to school. But I know the government is trying their best to help them. And Chinese people are so strong and brave that they aren’t afraid of anything difficult. Can the students go on studying now? Please tell me more about them.
I'm looking forward to hearing from you soon.
Yours, 
Tony

    My sister and me got the chance to have bike trip alongthe Lancang River calling the Mekong River in other countries. The Mekong River begin in a glacier on a Tibetan mountain. Then it becomes rapids as it passes through deeply valleys, travelling across western Yunnan Province. After leaving China and the high altitude, the Mekong becomes wide, brown but warm. Where it enters Southeast Asia, it makes wide bends or meanders through low valleys to the plain. In last the river delta enters into the South China Sea.
