Long summer in the northeast eats long summer. Eating long summer is to send spring to welcome summer and celebrate spring harvest. Long summer _ Breakfast, lunch and dinner are also different. After eating Long Summer, the farmer's door was padlocked. In the long summer season, wheat should be threshed, rape harvested, seedlings managed and summer tea picked.

On the day of long summer, the ancient Emperor of Heaven led doctors or officials to hold a welcoming ceremony in the southern suburbs of Beijing, dressed in Zhu fu, which meant summering in summer, and sacrificed raw meat, fresh fruit, grains, tea and other sacrifices to the ancient emperor. When this custom spread to the people, Chang Xia tried something new. Later, the custom of tasting three delicacies in summer gradually developed. Eating three fresh foods in long summer is also called "eating three fresh foods in long summer". Three chords are generally divided into "three chords of the earth", "three chords of the tree" and "three chords of the water". The three fresh plants are broad bean, amaranth and cucumber (amaranth, broad bean and garlic sprout). In fact, every place has its own three delicacies. It makes sense to eat these three kinds of delicious food. We eat broad beans because they just came into the market when we were in the long summer. Beans are also called germinated beans, and eating beans in the long summer won the lottery of "hair". The seasonal vegetable red amaranth, after eating amaranth, will gulp down the red soup in the bowl in order to get the "red" as the first color. Finally, cucumber has a lot of water, which is very suitable for eating in summer.
