You can soak the bird's nest you want for a week and keep it. You can take it out and stew it when you want to eat it. If you eat it once a day, you can take 20-35 grams of bird's nest (about 4-6 cups). If you take it three times a week, you can take 9-15g (about 2-3 cups) and soak the bird's nest at one time. When soaking the hair, just put the bird's nest in a clean porcelain bowl or glass bowl and pour in pure water to soak it. When we soak, we can do other things without consuming time at all.
