How to understand the joint and several responsibilities of the operators in the performance of the package tour contract?

during the performance of the package tour contract, operators should bear joint and several responsibilities to protect the rights and interests of tourists and improve the quality of tourism services and industry norms. In the process of package tour contract performance, the joint and several liability between operators means that multiple operators are jointly responsible for contract performance. When tourists are damaged in the tourism service agreed in the contract, not only the operators who directly provide the service need to bear the responsibility, but also other operators who share the responsibility need to bear the corresponding liability for compensation. This responsibility system helps to protect the rights and interests of tourists and improve the quality of tourism services and industry norms.
