Is it suitable to go to Hangzhou in February?

Not appropriate. Hangzhou in February is very humid and cold. It is not suitable for northerners to go to Hangzhou in February, but it is better to go in autumn. Hangzhou, referred to as "Hangzhou" for short, is the capital of Zhejiang Province, a sub-provincial city and the core city of Hangzhou metropolitan area. It is the capital of Zhejiang Province, the economic, cultural, scientific and educational center of the whole province, and one of the central cities in the Yangtze River Delta.
