Why are all the ancient windows made of paper? What if it rains and winds?

Netizen A: In ancient times, the measures to prevent rain and wind were not just to stick the windshield of the window: the window with paper paste was a very dense wooden lattice called window rib, which was coated with flour and cooked, and was evenly altered on it. Now the paper paste is very flat. In ancient times, the earliest houses had no windows. Later, in order to make the house brighter and more breathable, people opened the windows. Since then, windows have become an indispensable part of human living environment. Old window paper is made of cattail, rushes and ramie, and then painted with tung oil. .

Netizen B: One of the biggest advantages of paper window is that after mass production, the price of paper is the cheapest, and ordinary people can afford it, and the function of paper window is not inferior to that of traditional screen window, brocade window and silk window. During the Tang and Song Dynasties when paper was mass-produced, we all knew that tung oil was still very waterproof, so window paper was not afraid of rain, and it was also tough and easy to be destroyed. And brushing tung oil can be smoother and more durable. Moreover, in ancient times, the eaves of houses usually covered the windows, unless there was a storm, but even so, the rich people who used oiled paper windows were not afraid!
