Editor's note: 

Riding abouth 2,200 kilometers along the Sichuan-Tibet Highway south line, photographer Sun Xinqiang spent almost one month on his bicycle, from Chengdu, Sichuan province, to Lhasa, Tibet autonomous region. Sun said that no matter how skilled a photographer is, it is still hard to present the mystery and beauty of rivers, mountains, and sceneries on the plateau through camera.

His personal photography website is http://www.eduhope.cn/qp.htm and his email is 554267995@qq.com
