Can take-out be delivered from Shenzhen airport?

Of course. According to official website's inquiry about Meituan's take-out, you can order the take-out near the airport in the airport lobby, and the take-out from Shenzhen Airport can be sent in without entering the airport terminal. Takeaway refers to the food delivery service in the restaurant. The restaurant sends the prepared food to customers' homes or designated places, and customers can eat their own food without going to the restaurant in person.
