Japanese specialty food, flowing plain noodles, is connected by long bamboo poles, and then all the guests stand next to the bamboo, of course, at a certain distance, and then someone will always put the noodles into the water at the starting point, and then people downstream can take them away with chopsticks. After all, the people in front have taken the noodles away, and when the front is full, or it is too late to take the noodles, the people behind can take some turns. But this is the way that China tourists question, because your chopsticks are bound to pass through your mouth, then bring saliva, and then put it into the water to take the noodles, which means that your saliva will go straight down. In fact, this way is similar to China's dish in a plate.
