1. Prepare a few chestnuts and a chestnut peeler. It is best to use larger chestnuts, which will be more convenient to use.

2. First use the sawtooth side of the chestnut peeler to press hard on the front and middle of the chestnut.

3. Take away the chestnut peeler, and a small hole will be made in the middle of the chestnut.

4. Turn the chestnuts over, and then use the sawtooth side of the chestnut peeler to press firmly in the middle of the chestnuts.

5. After taking away the chestnut peeler, a row of small holes will be pressed out on the back of the chestnuts.

6. Use two fingers to hold both sides of the chestnut, and squeeze it into the middle with a little force, and the chestnut shell will be opened.

7. Insert the round end of the chestnut peeler into the gap between the chestnuts and chestnut shells to dig out the chestnuts.
