1. Choose low-gluten flour: Low-gluten flour contains less protein, which can make cookies more crisp. You can choose cake flour or ordinary flour.

2. Add grease: Adding enough grease can make cookies more crisp. Butter, vegetable oil or lard can be used.

3. Add sugar: Sugar can make cookies sweeter and crisper. White sugar, brown sugar or honey can be used.

4. Adjust the oven temperature: Turn the oven temperature higher to make the cookies more crisp. Generally speaking, the oven temperature can be adjusted to about 170- 180 degrees.

5. Control the baking time: Too long baking time will make cookies hard but not crisp, so it is necessary to control the baking time. Generally speaking, cookies can be baked 10- 15 minutes or so until the surface is golden yellow.

6. Cool cookies: Take out the baked cookies and put them on the iron net to cool naturally, which will make the cookies more crisp.

Through the above steps, you can bake crispy cookies at home.
