Let’s first talk about the “three big monsters” in Northeast China. One strange thing is "give birth to a child and hang it up." This is actually a Manchu custom. In the past, there were many wild animals in the forests in the Northeast, and it was not safe for children to put them on the ground, so they were hung up at a certain distance from the ground. The second weird thing is the "18-year-old girl hanging a cigarette bag". The proportion of women smoking in the Northeast used to be relatively high. It is said that smoking is also a way to keep out the cold. The third strange thing is "the windows are papered out". In the north, especially in winter, the cracks in doors are usually papered on the inside. Only in the northeast, windows are papered on the outside. This is necessary to deal with wind and rain. Because it is pasted on the outside, it can protect the wooden window lattice from rain corrosion and wind and sun, extending the service life of the window.
