It takes half a day to wash first and then soak in clear water. Do you want to eat it at noon, float it in the morning and eat it at night? Pay attention to one at noon, just don't use hot water and tap water, and the other is how many jellyfish you eat, which will fade and the salty water will not spoil. Don't float it for too long. Soak in clear water for several days, and all good jellyfish will spoil.
