Insect excrement tea, also known as Longzhu tea, is a specialty of Guilin, Guangxi and Chengbu County, Hunan Province. Locals put wild vines, aged tea leaves, fragrant trees and other branches and leaves in bare bamboo baskets, or string tea leaves together. After the larvae become maggots, they bite the tea leaves into beads and hang them outside the net for protection and camouflage. Beaded tea residue is insect excrement tea, which is called Longzhu tea by the people. It is particularly effective in inhibiting pantothenic acid in the stomach. Generally, moths do not choose new tea to lay eggs. Use a sieve to remove the residue and take its worm excrement, which is called dragon ball. Stir-fry in a pot, then mix and fry according to the ratio of honey: tea: insect excrement = 1: 1: 5, and the insect excrement tea will be processed.
