Did the paper doors and windows of ancient China become wet, soggy, and fall apart at the first sign of rain?
Interesting. Were there any other waterproof materials used in ancient China besides paper?
Yes, there were many other waterproof materials used in ancient China. Silk, for example, was often used in clothing and for decorative purposes because of its water-resistant properties. Some buildings were also constructed using materials like clay and stone, which were less susceptible to moisture damage.
