Polygonum multiflorum Thunb. is a perennial twining vine of Polygonaceae, with long and slender roots, fat tuberous roots at the end, reddish-brown to dark brown appearance, and growing in valley shrubs, hillside forests and stone crevices at an altitude of 200-3000 meters. Polygonum multiflorum Thunb. is a kind of Polygonum multiflorum Thunb. which is shaped like a human figure. There are two types: naturally formed Polygonum multiflorum Thunb. and artificially cultivated Polygonum multiflorum Thunb.: wild Polygonum multiflorum Thunb. According to the need, various humanoid molds are manufactured, and then the small Polygonum multiflorum Thunb is placed in the mold and planted underground, and when it grows up, it becomes an artificially cultivated humanoid Polygonum multiflorum Thunb. The artificially cultivated human Polygonum multiflorum Thunb. is symmetrical and full, just like a sculpture. At present, many human-shaped Polygonum multiflorum Thunb. on the market are mostly made of molds, so buyers should be vigilant and beware of being fooled.
