1. It will be the coldest time to visit Beijing in December and January. But it cannot be guaranteed that it will be snowy during your stay. In the north of China, it is hard to learn the regularity of snowing. Like in last winter, it snowed less than usual. But in the beginning of 2008, it snowed a lot. So it is impossible to predict this.

2. Usually the scenic spots will not be closed due to the snow unless it becomes a disaster.
