In what dynasty was the tea shredder invented?

There is no historical record of a specific dynasty that invented the "tea shredder."

The process of shredding tea leaves, known as "plucking", is a traditional practice in tea production that likely predates any specific dynasty. It was essential for breaking down the leaves to expose their surface area for oxidation and create the desired flavors and textures in different tea types.

While specific tools and techniques for shredding tea leaves may have evolved over time, it's unlikely that a single dynasty is credited with inventing a specific "tea shredder."

Instead, the practice of shredding tea leaves is a part of the long and diverse history of tea cultivation and processing, developed and refined by various cultures over centuries.
