During Chinese festivals, Chinese people don't work. They shop. They eat with their family and friends. They travel.
Different festivals have different meanings to different Chinese people.
During festivals, most shops and shopping center offer huge discounts.
It is not only a commercial strategy. As a customer you can really get some good deal if you shop during festivals.
The worker festival in Mai and the national holiday in October are the two festivals during which you can benefit from the best discounts!
