Three no products.

Three-no products generally refer to products with no production date, no quality certificate, no manufacturer, and unknown origins. Another way to say it is that the three-no product is a product without the production factory name, the second no production factory address, and the third no production health license code. The "People's Republic of China and Domestic Product Quality Law" stipulates that there must be a Chinese factory name, Chinese factory address, phone number, license number, product logo, production date, Chinese product instructions, and if necessary, qualitative or suggestive instructions. Etc. Anything missing is considered a substandard product. Any product that lacks one of the above requirements can be regarded as a "three-no product".
