1. Sales strategy: Hongyun cigarettes may only be sold locally in Yunnan to support the local economy and employment. Because Hebei Province is far from Yunnan and the transportation cost is high, it may not be sold in Hebei Province.
2. Production plan: The production plan of Hongyun cigarette may be affected by many factors, such as raw material supply, capacity limitation, market demand and so on. If the production plan cannot meet the sales demand, it may lead to temporary shortage in some areas.
3. Regional agents: The sales channels of the tobacco industry are usually handled by regional agents. If the agent in Hebei Province has not signed a sales agreement with the manufacturer of Hongyun cigarettes, or the agent has insufficient inventory, there may be no supply in Hebei Province.
Please note that the above is only a possible explanation, and the specific situation may be different due to factors such as market environment and policy adjustment. If more detailed information is needed, it is recommended to contact local tobacco sales channels or relevant institutions for consultation.
