The place where the jade is produced, the surrounding environment contains a lot of water, and the water molecules in the jade are very rich. In areas with heavy water shortage, it is natural to not maintain water loss, especially those kinds of thick jade water is easier to lose water. When it is dehydrated, it will become dry. When it is dry, it will produce smashing and cracking. If it is split, the jade will lose its beauty.
