In Yantai, we pay great attention to eating jiaozi before departure, and welcome guests to eat noodles, commonly known as "getting on and off the car with jiaozi". Eating jiaozi is a metaphor for trying to make things easier and travel smoothly. Eating noodles is a metaphor for feeling long and far away and stopping our legs. The wisdom of ancient people is not only used in science and technology, medicine and so on. You can also use your imagination in food.
