John started the Lookatchina.com website after his trip back to Shanghai (he was born in Shanghai) after staying in U.S. for six years. (I am not sure whether John from lookatchina.com is the same John who won the Top Commentor of the Month award on this site)
John took many pictures in Shanghai and covered almost all major places in Shanghai. You can find pictures of Xujiahui, Shanghai Jiaotong University, Yuyuan, Nanjing Rd., Metro, Buses… almost all aspects of Shanghai. I like the photos he took.
Please visit his Shanghai page. (I knew his site by recommendation of Kathy).
