I have gone to Guangzhou I stayed there for 4 days.The air there was not fresh,but the city was so boom.Many people waiked quickly on the street ,from these I can felt about the rapid cadence .The secoud day I have gone to visit some colleges.Though it was weekend ,the students were study so hard .The third day I have gone to Zhuhai .Zhuhai is a beautiful city and I can overlook the blue sea.The air with some sea smell blowing to my nose.How comfortable!
