hi we are visiting china in mid October, what is the weather like? recommended cities to visit?

In northern China, it shall get a little bit cool during that time, with the highest temp of 20-23C and lowest of 10C. Cloudy days would be the majority, while several rainy days may happen. You need to prepare light jacket, both long-sleeveda n short-sleeved shirts and regular jeans.

In southern part, it shall be still warm even hot and the highest temp may reach 30C. Sunny days would make your a pleasant trip. Summer clothing is enough~
