Planning to go back to Singapore for visit then fly to Guangzhou, stay for couple of days. Would like to take a train from Guangzhou to Yangshuo, Guilin, Chongging and Chengdu, stopping for 3 to 4 days in each stop. I have about 22 days to spend before going back to Wisconsin. Is there an International Airport in Chengdu?? I would like to take plane from Chengdu to Chicago (USA).I'm trying to get a plane ticket from Chicago-O'hara to Singapore to Guangzhou and later connected from Chengdu airport to Chicago-O'hara,USA. I would like some advices about train connection not forgetting the Chengdu Airport.
