What kind of jacket/coat to pack in Tianjin?

Hi, since the highest temperature then will be about 13C and the lowest one can be about 3-5C, I suggest you take along the overcoat, sweater and Long John.
You will meet rainy day on 2nd Nov. but not heavy, so you have to make preparation for the rain and sudden temperature fall.

Thanks so much for the quick reply! Now I know I will prepared for the cold :)
