When most people wash fungi, they just dip them in water a few times and take them out. In fact, this will make the mushrooms dirty! Because many mushrooms are covered with gills on the back, you should soak them in warm water for about 1 hour, and then stir them in one direction with your hands for about 10 minutes, so that the gills of mushrooms can slowly open and the sand carried inside can fall and settle. Especially dried mushrooms, don't take them out directly and put them in water after soaking, and pinch off the water to clean them. Should be soaked in enough water, and then gently take out the mushrooms and rinse them with water.
In addition, it's best to soak mushrooms in hot water first, soak them soft and squeeze them dry (the water for soaking mushrooms for the first time must be kept, and clear soup should be taken for later use when settling), put the mushrooms in another container, grab some edible salt, and then rinse the salt. The first bowl of water for soaking mushrooms is precipitated and clarified, so remember to put it in the pot when making soup, so the soup will be more delicious.
