In February winter is still in full swing in North China. There is not much change in February from January weather in the North. In Central China, it is slightly warmer than in January. Signs of spring begin to appear by the end of February in Central and South China.
Layers are essential for winter travel.
North: It is freezing. Warm clothes such as overcoats, long underwear, and fleeces are recommended.
Central: The temperature is around 0°C (32°F). A down jacket and a wind-proof jacket are needed.
South: It is warmer. Long sleeves and pants, and a wind-proof jacket are recommended. Thermals are often worn indoors on the coldest days, as there is usually no central heating in the South.
It is very cold in North China, and cold and humid in Central China and parts of South China.
The New Year period (January 23 to February 6, 2012) and a week or so before, sees huge crowds in transit everywhere in China. The major transportation hubs such as airports, railway stations and bus terminals get overcrowded. Trains in general are likely to be fully booked days in advance, certain popular flights may be sold out, and even regional and municipal buses can be so packed they don't stop. Shopping malls are often teeming with life, while public gatherings and processions can fill up plazas and block sidewalks. See Chinese New Year Travel Guide
