  1. Resource Protection: Ancient buildings, cultural relics and other resources in the ancient town are precious and fragile. By implementing the joint ticket system, the number of tourists can be limited and the pressure and damage to the scenic area resources can be reduced.

  2. Reasonable Allocation: Different attractions in the ancient town may be owned by different management units or individuals. The joint ticket system helps to integrate resources and improve operational efficiency.

  3. Service quality: Through the joint ticket system, scenic spots can be managed and maintained in a unified manner, improving service quality and ensuring tourists’ visiting experience.

  4. Economic Benefits: The scenic spot can earn income by selling coupons, which can be used to maintain the daily operation, maintenance and protection of the ancient town.

As for whether it is free, it depends on the operating policy and financial situation of the scenic spot. Some scenic spots may be open for free, while others require tourists to purchase tickets to support the operation of the scenic spot. Huishan Ancient Town may belong to the latter, so you need to purchase a combined ticket.
