Someone brought back a kind of black tea from England, not in the shape of tea, but in small particles. What kind of tea is this?

Tea is a traditional popular drink in Britain, with an average of 8 people drinking tea per 10. China consumes nearly 200,000 tons of tea every year, accounting for 20% of the world's total tea trade, ranking first in western countries and known as the "tea kingdom". English tea usually adds milk, sometimes sugar, but more often orange slices and jasmine are added to make so-called Duke black tea, jasmine black tea, jam black tea and honey black tea. Small black tea is one of the processed black teas mentioned above.
