Winter storm disaster

Nothing is impossible. The cities always warm in southern China became places freezen. All the feathered clothes in the city were sold out to the People who did not need it for about 50 years.

In the summer, the mouse became disaster in Hunan, Hubei province, in the winter, the snow and ice became disaster in that area.

Is there any relation between the disasters and the Yangtz long river Hydraulic engineering?

Take care of the environment.
