Today lots of people order takeout（点外卖） on different Apps. Did people also order takeout in the Song dynasty（宋朝）? The answer is yes!
At that time，people didn't have phones. They couldn't use the Internet. But they could order takeout! Some restaurants had takeout workers. They went out and yelled（吆喝）their dishes. People ordered，and the workers took the food to people's houses.
Now，takeout workers use e-bikes. But in the Song dynasty，there weren't any bikes. Takeout workers walked to send food. How could they keep food warm? They used a special box!
