Everyone has a responsibility, but legally speaking, the newly married family is an agreement signed with the wedding company, or a de facto contract. They can only pursue the wedding company, which entrusts others to operate, which is the wedding company's own business. The wedding company can only claim compensation from the manager according to the customer's recourse requirements.
If the wedding company explains that it belongs to the introduction business, the responsibility will be much smaller. Belong to joint and several liability.
