What clothes should I wear to travel to Shanghai during the Spring Festival?

During the Spring Festival, the weather in Shanghai is the worst in a year. It's cold (about zero) but humid, so it's likely to rain. The human body feels much worse than a sunny day at -5 degrees.

However, the conditions in Shanghai are better and the indoor air conditioning is more adequate. Both buses and subway cars have heating, and shopping in the mall will feel too hot.

Down jacket is needed, and it is better to wear it when playing outdoors. Sweaters and down jackets will do. Enter the indoor place, take off the down jacket and hold it in your hand. Wear less sweaters and don't wear woolen pants to avoid being too hot and uncomfortable indoors.
