the sale of rambutan is not completely prohibited, but in some areas. In 222, Yuhang Branch of Hangzhou Public Security Bureau destroyed an illegal processing den soaked with "Poisonous Rambutan". The picture taken shows that bags of rambutan are soaked in the cement pool, and the room is filled with pungent sour taste. There are vats of preservatives piled up everywhere on the ground, and many small holes are punched on the surface of plastic bags to facilitate soaking rambutan. This illegal processing of dens is illegal, and the quality of rambutan cannot be guaranteed, which may cause harm to consumers' health.
