1. 200 grams of dried soybeans are soaked in water for 8-10 hours (soak in the refrigerator in summer)
2. Wash the soaked soybeans with clean water, add 1000 grams of water, and grind them into a thick soy milk with a juice machine (or use an ordinary cooking machine), and filter the ground soy milk for later use
3. The soy milk is boiled thoroughly on the heat, do not heat up the whole process, to prevent the pot from overflowing
4. The boiled soy milk skimmed the floating powder and turned off the heat
