Hainan New Oriental can learn: (1) Put the pot on the fire, add clean water (80% full), and wait until the water is heated to 55 ~ 60℃ (there is no thermometer, you can test the water temperature by hand. The method is: first put your hands in a cold water basin, then put them in a pot and stir them quickly. If you can stir it continuously for 3-4 times, your hands will be too hot to stir any more, and then you can scald the ducks in the pot.

(2) When ironing, first hold the duck's paw with your left hand, immerse the duck's head in the pot and shake it by hand. Then put the duck into the pot and move it back and forth along the duck with a small wooden stick to let the duck feathers penetrate evenly. The duck is scalded in water for about 3 minutes (try to pluck its hair by hand when scalding). When the duck feathers are easy to pull out, it means that the duck feathers are burnt, and the duck should be taken out immediately.
