Chengdu is known for a “laid-back” city. A relaxing teahouse culture and a lively nightlife that mix beer bars and Sichuan opera shows contribute to their unique charm. Hundreds of Sichuan dishes and spicy hotpots sure impress visitors. If lucky enough, one can see mountains cover by snow from the city even in summer, which is one of the most amazing sight there. The city increased green space since 2009 as a result of an air pollution. With over 10 million tourists visit the city every year, Chengdu has so much to offer. Unless you have time, you may go there to explore it by yourself.
