It has been in winter in Beijing. The weather would be windy and the temperature will be below zero. Xian is cold at that time too, warmer than Beijing. It is about 15 degrees at daytime and below 10 degrees at night. Last year, the first snow had fellen at that time in Beijing and Xian. Shanghai is warmer. About 15 degrees in Mid-November and cooler later. Need to wear thin sweater and coat. Guilin is the warmest, but still cool down in late November. The weather changes fast here. Warm today and it may rain and need to wear thick coat the other day. Anyway, not a good time to see Guilin at that time.
