1. Make tea eggs. Some use brewed tea leaves to cook, some use tea powder. The best is to use black tea; ordinary black tea is inexpensive and makes tea eggs with reddish color and delicious taste. The method is to boil eggs first, gently crack the shells, then add tea leaves to continue boiling for better flavor absorption.

2. Make tea pillows. Don't discard used tea leaves; spread them on a board to dry, accumulate them, and use as pillow stuffing. It's said that because tea is cooling in nature, tea pillows can refresh the mind and enhance thinking ability.

3. Repel mosquitoes. Dry used tea leaves and burn them at dusk in summer to drive away mosquitoes, with the same effect as mosquito coils, and absolutely harmless to humans.

4. Help plants grow and reproduce. Brewed tea leaves still contain nutrients like inorganic salts and carbohydrates. Burying them in garden or flower pots can help plants develop and reproduce.

5. Sterilize and treat athlete's foot. Tea contains large amounts of tannic acid, which has strong sterilizing effects, especially effective against filamentous fungi that cause athlete's foot. So, people with athlete's foot can boil tea into strong liquid to wash feet nightly, and it will eventually cure with persistence. However, this requires continuous effort with no immediate results. It's better to use green tea, as fermented black tea contains much less tannic acid.

6. Eliminate bad breath. Tea has strong astringent effects. Regularly holding tea leaves in the mouth can eliminate bad breath. Frequently using strong tea as mouthwash has the same effect. If you don't like drinking tea, you can hold brewed tea leaves in your mouth to reduce bitterness while still getting benefits.

7. Care for hair. Tea can remove grease and dirt, so after washing hair, rinsing with tea can make hair black, soft, and glossy. Plus, tea contains no chemicals, so it won't damage hair or skin.

8. Wash silk clothing. Silk clothes are most vulnerable to chemical detergents. If you use boiled tea water from used leaves to wash silk garments, it can maintain their original color and make them look new. It has the same effect on nylon fiber clothes.

9. Use used tea leaves to wipe mirrors, glass windows/doors, furniture, sticky surfaces, and dirty leather shoes; it can also remove stains from dark-colored clothes.

10. Remove fishy smell from containers by boiling used tea leaves in them for several minutes.
