Hi,
I saw your post that you have travelled to Beijing during the winter season. Planning to bring my family also (with 3 teenager kids as well) on this month but not sure if we can bear the negative temperature and if there are places to visit even during winter like the Great Wall. Appreciate if you can share your experience. Thanks.

There are many pleases worth visiting in China. Our group have a great fun at cities like Kunming, Dali and Lijiang (the temperature and weather is good there). Also, Sanya have really beautiful scenery. But winter is a hot season for traveling in Sanya, thus the cost is higher than other cities. To make your trip more smooth, I suggest you to find a trustworthy agent and make a better arrangement for you. A good tour guide is very important, he can slove the problem of language barrier. Hope this can help.
