What are the common quality issues with tea bags?

The quality of tea bags is related to the quality of the raw material tea. Bagged tea has both good and bad qualities, not all of which are inferior.

Perhaps it is a Chinese tea drinking habit, where people generally prefer to drink large leaved tea and emphasize washing the tea before brewing it again. Additionally, a pot of tea needs to be brewed several times.

But this is quite troublesome, suitable for leisurely times. Meet three or five friends and slowly brew a pot of tea, where everyone can chat while drinking tea.
