•Avoid Peak Holidays:
It is not a good idea to travel in China during Chinese holidays when huge numbers of Chinese people are travelling around. The busiest three national holidays in China are Chinese Spring Festival (usually in late Jan or early Feb.), International Labor Day (May 01 to 03) and National Day (Oct 01-07). Spring Festival is an especially crowded time to travel. The advantage of being in China at this time is that you will get the opportunity to experience "first hand" the significance of these celebrations in Chinese culture.
An umbrella should be carried in case of unexpected rainfall, and sun-glasses and sun-block cream are advised to protect you from high UV, especially in summer.
As Zhejiang is influenced by the Southeast Monsoon, the rain in the mountain areas here is much more than that in coastal areas; and the weather is moist; tourists should bring your rain gear.
