Even if there is no mobile phone, the room service in Song Dynasty can still order food in two ways. One way is to order food through the message of the residence, and the other way is for the restaurant to send the bartender to the vicinity of the residence where the food is often ordered to be sold.

first of all, in the first way, in ancient times, the people who could afford to go to pubs and restaurants were basically wealthy families with rich family background, and the servants were the most important thing in such people's families. Therefore, when the owner of a house wants to eat food outside, Ding can be used as a mouthpiece to transmit the message. What the owner wants to eat and eat the food in that hotel, he only needs to tell Ding to order food at the hotel, and then the hotel waiter will deliver the food.

the second type is that the bartender sent by the hotel and restaurant makes inquiries in the courtyard of the permanent guest's house, or sells in the area where some rich people live. If anyone wants to buy, he will call the bartender to order. After the guest orders the meal, the bartender returns to the restaurant to report the guest's order to the chef, and sends it to the guest's home after the chef completes it.

besides these ordering methods, the tools for food delivery have always been very curious. In Song Dynasty, the tools for food delivery and insulation were called food boxes, which were commonly used in ancient times. We can often see food boxes from some film and television dramas. The food box is made of bamboo, and the center is added with ceramics as a warm plate, so that the food delivered is still warm.

nowadays, the take-away industry is developed, but it is unexpected that there is also a food delivery service in the Song Dynasty. This little detail found on the Riverside Scene at Qingming Festival does not make people feel how meticulous Zhang Zeduan, the painter of Riverside Scene at Qingming Festival, observed the folk life in Song Dynasty, which provided great help for later generations to study the social climate at that time.
