it is very complicated to make Eucommia ulmoides leaves into Eucommia ulmoides tea, and it takes many procedures and repeated frying to make it. It is very simple to stir-fry tea by machine, but it is very complicated if it is made by hand. One person can make two or three kilograms at most a day. I saw Eucommia ulmoides tea made by hand in the "Green Neighbor" shop on Taobao. The picture is very detailed, and the fire is made with wood, so the tea made is more fragrant.
