I will be in shanghai dec 5 to 10. What will be the weather.What clothes to bring, footwear.? Thanx

Actually, it is a little hard to tell you the detailed information, but according to past two years' weather records, it will be cool, not cold then. You will get the average temperture of about 10C or around. Based on the past two years, it rained a little during that time, so maybe simple raniy gear needs to be prepared.
As for the clothes, the thin sweater and a jacket can be ok. Sports shoes are proper then.

Thanx andrew for the info. Actually, it will be my first trip to shanghai this december.
