What are the customs and customs in the three northeastern provinces?

The special customs and customs in the Northeast are the "Three Northeastern Weirds".

The first strange thing: the windows are papered outside. Because the Northeast is cold, so in the winter, paper strips are used to paper up the gaps in the windows. This is not strange, but the strange thing is that the windows are papered outside. That is because the winter in the Northeast lasts for 4 or 5 days.

For months, the paste is easily wetted by water vapor when left in the house, and is easily damaged by the wind through the cracks in the windows.

So in the early years, before the current aluminum alloy windows existed, every house in the Northeast looked like this.
