Read a passage about the history of food delivery.

The history of food delivery in Korea goes back much further than one
might imagine.
The earliest food delivered on record is naengmyeon in
the Joseon era.
In his book, the scholar Yunseok Hwang (1729-1791)
mentions that he ordered naengmyeon for lunch with his colleagues on
the day after the state examination in July 1768.
It appears that
naengmyeon, a summer dish enjoyed in the royal court, had gained
popularity among noblemen, leading to the introduction of delivery
services.
In Yuwon Lee’s book, it is recorded that King Sunjo (1790-1834)
of Joseon ordered his servants to buy naengmyeon and bring it back to the
palace so that he could eat it while looking at the moon.
