Introduction to the Cloud Peak Picture: There are very few calligraphy and paintings hanging in the Hu family's mansion, and most of them are naturally formed cloud peak pictures hanging on the screen. Firstly, because of the humidity in the south of the Yangtze River, calligraphy and paintings are not easy to preserve; secondly, this type of jade stone is mostly naturally formed and can present a very beautiful appearance without carving, so it is often used as decoration and embedded in walls.
