planning to go to Guangzhou on first week january,what's weather like?

Hi, according to the weather records of the past years, the highest temperature then will be around 18C and the lowest is 5-7C. Sometimes, it might rain a little. Thus I suggest you take the cardigan, jacket and Long John to keep warm, especially at cool night.
The famous shopping area there should be Shangxiajiu Road, therefore, I suggest you go to the nearby Home Inn Changshou Road or Seven Days Inn, both of which have a generally-accepted price.
