Green tofu

Also known as Guanyin tofu. The raw material is a small woody shrub called Tofu Chai, which is mostly wild at the edge of streams and other places, and there are many bamboo pits in small villages not far from Sixi. Mainly pick and wash the leaves of Tofu Chai, take its juice, dilute it with appropriate amount of water, then add a little cool toothpaste, stir well, cover it, place it, wait for freezing, and add some soup as you like to eat.
