The original tea bags were simple square single-bag shapes. When such tea bags were put into water, the tea leaves would be concentrated in the tea bags, and the brewing speed was very slow. However, due to its simple form and crude packaging machinery, it is still used by most businesses.

With the popularity of flower and fruit tea, ordinary tea bags cannot accommodate the expansion of fruit grains and petals due to their small space, so diamond tea bags began to appear on the market.

The emergence of tea bags is not to reduce or improve the quality of tea, but to facilitate portability and brewing, and more for convenience. Naturally, it is inevitable to damage the appearance of the tea leaves. But for tea lovers who are away from home, tea bags also have their advantages.

In fact, tea bags and tea leaves are like the difference between instant noodles and handmade noodles.

People who love tea usually do not use tea bags to make tea, because they are full of tea leaves and do not have the fragrance and the beauty of the tea leaves flowing in the cup.
