Is the inner container of rice cooker with more than 20 yuan of goods poisonous?

In Pinduoduo, a rice cooker with a price of more than 20 yuan is poisonous. The price of rice cookers in 20 yuan is low, the quality of products cannot be guaranteed, and problems may occur between meetings. The materials used are all low-priced and unsafe materials, and the materials used in rice cookers are not food-grade, which will cause harm to the body if eaten. The really cheap electric cooker circuit is also prone to problems and dangers, which brings great hidden dangers to the safe use.
