Why are "those" cigarettes being investigated?

The case is that Ai is the owner of a tobacco hotel and has obtained a tobacco monopoly retail license. This year's Dragon Boat Festival, a brand of cigarettes in his shop was sold out. In order not to delay the business, in a hurry, he approved a few cigarettes from his peers' tobacco hotels at wholesale prices and sold them in his own shop. But who knows that day happened to meet the routine inspection of tobacco monopoly law enforcement personnel. Law enforcement officers registered and saved cigarettes in advance, and told Ai that the cigarettes registered and saved in advance belonged to cigarette strings. In this regard, although he actively cooperated with law enforcement officers, he still had doubts: the goods were imported from tobacco companies, how could they not be sold? According to Article 25 of the Regulations for the Implementation of the Tobacco Monopoly Law, an enterprise that has obtained a license for tobacco monopoly wholesale enterprise shall engage in the wholesale business of tobacco products within the business scope and geographical scope specified in the license. Enterprises or individuals that have obtained tobacco monopoly retail licenses shall purchase goods from local tobacco monopoly wholesale enterprises and accept the supervision and management of the tobacco monopoly license issuing organs. Ai belongs to an individual who has obtained a tobacco monopoly retail license and should purchase goods from a local tobacco monopoly wholesale enterprise, that is, a local tobacco company. Although the cigarettes "wholesale" by peers are also imported by peers of local tobacco companies, they belong to secondary wholesale and do not belong to legal purchase channels. "Wholesale" cigarettes are all printed with their peers' spray codes. If it is sold in Ai's store, it is a serial code sale, and cigarettes that are "not bought in local tobacco monopoly wholesale enterprises" should be investigated and dealt with.
