The mix of shrimp and citrus with garlic and onions is a long observed food combination. You can add in some peapods or veggies to make this dish the way you like it during the time you cook the noodles. Lime shrimp dragon noodles are quick and easy to make and have a long history.
The noodles are believed to have been invented by a chef working for the emperor during the Ming dynasty. During lichun, the chef made some unusually long and thin noodles which delighted the emperor, and later became popular among peasants as well. Because of their association with dragons, the noodles began to be eaten during the Longtaitou (lit. “dragon raising its head”) festival, which celebrates dragons and the role they play in bringing the Spring rains. Now that day is celebrated during the 2nd day of the second month of the chinese calendar.
