Destinations without crowd

Hi, we've been living in Shanghai for 3 years and have already visited Hangzhou & Suzhou, Beijing, Guilin, Hong Kong, Yunnan, part of Xinjiang (Kashgar), as well as Taiwan, Laos, Myanmar, Cambodia. We are now planning our next trips for October 1st national holiday and CNY 2016 (1 week each time), and wondering if there is any place in China or South east Asia with a normal number of quiet tourists during national holidays ?? Any ideas very welcome ...
