what is weather like between Dec 12-22 in Nanjing-Beijing areas. Thank you.

Nanjing and Beijing is not close to each other and the weather of these two places varies. The temperature in Beijing is about -5 degree to 8 degree. If it snow, the temperature in Nanjing is similar, maybe -3 degree. We can not predict the weather of this year. So, pay attention to the weather forecast before leaving. Generally the weather report for next 2-3 days is believable.
