The primary use of tea leaves is as a beverage, offering an excellent drink with color, aroma, and flavor. Besides brewing tea, tea leaves also have high practical value. Some of these uses are introduced below:

1. Brew Tea Eggs. Some use steeped leaves, others use tea dust. Black tea is best; common black tea is inexpensive and yields tea eggs with a reddish hue and fragrant taste. The key is to boil the eggs first, lightly crack the shells, then add tea leaves to the water and continue boiling to allow better flavor absorption.

2. Make a Tea Leaf Pillow. Don't discard used tea leaves. Spread them on a board to dry, accumulate them, and use them as pillow stuffing. It is said that due to tea's cooling nature, a tea leaf pillow can refresh the mind and enhance thinking.

3. Repel Mosquitoes. Dry used tea leaves and ignite them at dusk in summer to repel mosquitoes, with an effect similar to mosquito coils, and it's absolutely harmless to humans.

4. Aid Plant Growth and Propagation. Brewed tea leaves still contain nutrients like inorganic salts and carbohydrates. Burying them in flower beds or pots can help plants develop and propagate.

5. Sterilize and Treat Athlete's Foot. Tea leaves contain a large amount of tannic acid, which has strong sterilizing effects, particularly effective against the filamentous fungi that cause athlete's foot. Therefore, people with athlete's foot can boil tea leaves into a strong decoction to wash their feet nightly, and over time, it may cure the condition. However, one must be persistent; significant results won't appear quickly. It's best to use green tea, as fermented black tea contains much less tannic acid.

6. Eliminate Bad Breath. Tea has a strong astringent effect. Frequently holding tea leaves in the mouth can eliminate bad breath. Gargling with strong tea also has the same effect. If you're not fond of drinking tea, you can hold steeped tea leaves in your mouth to reduce bitterness, which also works to some extent.

7. Care for Hair. Tea water can remove grease and dirt. After washing hair, rinsing with tea water can make hair black, soft, and glossy. Moreover, tea water contains no chemicals and won't harm hair or skin.

8. Wash Silk Garments. Silk clothing is most vulnerable to chemical detergents. If you use water boiled with steeped tea leaves to wash silk clothes, it can maintain the original color and make them look bright and new. Washing nylon fiber clothes has the same effect.

9. Absorb Dust. Use steeped tea leaves to wipe mirrors, glass windows/doors, furniture, adhesive paper, or dirty leather shoes; they can remove stains from dark clothes. Dry the residual tea leaves and sprinkle them on carpets or rugs, then sweep them away; the tea will take all the dust with it. Tea leaves have strong absorbency, capable of absorbing not only moisture but also dust.

10. Remove Fishy Odor from Utensils. Put used tea leaves in the utensil and boil for a few minutes to eliminate the fishy smell. When steaming fish or seafood, after the water in the steamer boils, open the lid and sprinkle a little tea broth to ensure the seafood is sweet and delicious without the annoying fishy smell. Alternatively, after cleaning fish or seafood, wash them once more with cold tea water to remove the fishy taste and ensure tender flavor. However, it's generally not recommended to put tea leaves directly into the steamer, as it may破坏 the seafood's freshness.

11. Remove Furniture Odors and Grease. Wipe old furniture with a soft cloth soaked in tea water to remove grease and make it shine like new. New furniture may have a pungent smell of paint, formaldehyde, or rubber/leather. Wipe it several times with strong tea water to remove the odor. You can also place some tea leaves in a stocking and put it in a new wardrobe as a deodorizer, which works very well.

12. Use Tea as a Car Windshield Cleaner. On rainy or snowy days, drivers often feel the front windshield never gets clean enough. If no glass cleaner is at hand, you can use tea water instead to wipe the windshield. It works quite well. Additionally, placing some tea leaves in the car as a deodorizer is more effective than common air fresheners.

13. For Burns or Scalds. In case of accidental scalds or burns, take an appropriate amount of tea leaves, decoct them into a strong broth, cool it quickly, and immerse the affected area in the tea water. Alternatively, apply tea water to the wound 4-5 times a day.

14. Make Delicious Lei Cha (Pounded Tea). Using tea leaves and roasted peanuts, sesame seeds, rice, along with ginger, pepper, and salt as ingredients, put them into a ceramic or wooden mortar. Rotate and pound with a wooden pestle to grind them into fine powder. Then take it out and brew with boiling water to make uniquely flavored Lei Cha. Lei Cha has an ivory yellow-white soup color and a savory aroma, unforgettable to those who have tasted it.

15. Create Realistic-looking Vintage-style Photos. Materials: 1 bag of black tea, several new photos, boiling water. Method: 1) Place the tea bag in a lunch box, pour boiling water, and let steep for about 2 minutes. 2) Remove the tea bag, place the new photos flat into the lunch box with the tea broth, and soak for about 5 minutes. (Note: The broth is still very hot.) 3) Remove the photos, clip them with a clothespin, hang them on a clothesline, and let them air dry naturally (must air dry naturally, do not wipe). 4) Once dry, take down the photos. The brand-new photos will have turned into slightly yellowed old pictures, achieving a deceptively realistic effect.
