Moldy Chinese paintings can be treated by scalding, and now some people try to bleach them, but no matter how they are treated, they can't be completely restored to a moldy state, so we should try our best to avoid moldy calligraphy and painting. Finally, the landlord said, "There is no painting on the white rice paper", which means what to do if the rice paper is moldy. If the rice paper is moldy, take it to a dry and high-temperature place and let it dry naturally (high temperature refers to the high temperature like summer, not the high temperature of steelmaking). In addition, pay attention to shelter from the wind, and don't be blown by the wind for too long, so as not to be weathered and run away. Once alum is weathered, rice paper is basically useless.
