2. Gently brush the front and back of the leaves with a soft toothbrush. Don't care too much, lest you brush the leaves.

3. Pour a proper amount of cold water into the pot and bring it to a boil. Put the washed leaves in and cook for about 2-3 minutes. Take it out, rinse it with water and soak it in water.
