I can't buy four cigarettes. What happened?

According to the query of official website of China Tobacco Bureau, the reasons are as follows:

1. Epidemic factors: During the epidemic period, some tobacco factories and supply chains were affected, the production capacity decreased, and the production and supply of some brand cigarettes were affected to some extent.

2. Market regulation: In recent years, the state has gradually strengthened the management and regulation of the tobacco industry, and constantly raised the tobacco tax rate and price. In order to reduce the adverse effects of tobacco on social health and reduce the number of smokers, the price of cigarettes has been adjusted to some extent.

3. Supply chain problem: The supply chain problem of some tobacco industries is not perfect. Facing the increasing demand and market fluctuation, the supply chain management and adaptability of some brands are insufficient, which leads to some difficulties in cigarette supply.
