Cigarettes from all over the country are produced and sold by tobacco monopoly bureaus (companies) in various provinces. How to produce, quality control, output and so on are all controlled by the manufacturers themselves, but the sales are supervised by the Tobacco Monopoly Bureau.
Tobacco sales in each province are regulated by tobacco companies under the provincial tobacco monopoly bureaus according to the needs inside and outside the province. Because cigarettes are high-tax products, when regulating tobacco from other provinces, provinces generally exchange them according to the proportion of goods and prices, which are generally divided into high-grade cigarettes, middle-grade cigarettes and low-grade cigarettes, and each level is distributed according to tax money.
