It's April 20 10. Why is it so cold now?

Landlord, the reason why the weather will be cold is that the strong cold air in the north continues to go south recently, resulting in a large area of rain and snow in the country, which makes the temperature in most parts of the country 2~3 degrees lower than normal. ............

So the landlord should pay attention to keep warm. ........

It may not pick up until late April. ........
