Meituan special delivery is a take-away delivery service, and its scope is limited to a specific area. If your place is not within the scope of the special service provided by the US delegation, you can't use this service to check in. This is because the special delivery of Meituan needs to ensure that orders can be delivered to customers in time and accurately, and out-of-range locations will lead to delivery delays or other problems. Therefore, in order to ensure the quality and efficiency of service, the express delivery of Meituan is not allowed to be signed outside the scope.
