Hi I planed to travel to Shenzhen on 11Jan to 17 Jan , wI'll it rain around these time ?

According to the previous statistics, the temperature may range from 50 F to 70 F during that period of time. And yes, it may have several rainy days. But it is hard to tell right now. Keep an eye on the weather report. Even if it rains, it won't influence the sightseeing a lot. You can prepare jackets, thin sweaters, overcoats, jeans and pants. :-)
