Underground factories without any production qualification illegally purchase tobacco leaves and some raw and auxiliary materials that do not meet the quality requirements under the cover of pigsty and cowshed in remote areas, and illegally produce cigarettes. White-coated cigarettes are cigarettes without trademarks or brands. Cigarettes are monopoly commodities, and tobacco monopoly laws and regulations stipulate that cigarettes sold must have registered trademarks, and the packaging of cigarettes is all-inclusive registered trademarks, that is, all the pictures displayed on the packaging of cigarette cases are registered trademarks to prevent others from counterfeiting.
