Now I am happy to see that they are in top 3 as "the happiest cities in China" according to a recent survey.
"What is China’s best and most favoured city to live in? Where do people feel at home, with good facilities and enough things to do, at a reasonable price level? It is not Beijing, nor Shanghai, Shenzhen or one of the other large metropolises in China. According to a recent survey, the best city to live a happy life with your family is Hangzhou, the capital city of Southeast China's Zhejiang Province."
