At five o'clock every day, that is, from three to five in the morning, people in Kaifeng have already started a new day, and the morning market has already started to sell. People who came early sat at the city gate waiting to open the door, some were singing, gossiping and doing small business. Most wine shops sell wine with lights on, each serving is 20p, as well as porridge, rice and snacks, facial cleanser, tea medicine and so on. At dawn, the butcher shop opened, and there were nearly 100 workshops to kill pigs and sheep ... Such a scene appeared in the article "People Come in at Dawn" in the third volume of Tokyo Dream. The picture shows a partial picture of the Riverside Scene at Qingming Festival, and there are many similar descriptions in Tokyo's love love love. A Dream in Tokyo is an essay by Meng Yuanshen in the Song Dynasty, and it is a book depicting the urban customs of Kaifeng, the capital of the Northern Song Dynasty. Most of the records are about the daily life scenes of nobles and ordinary people living in Tokyo during the historical period from Song Huizong Chongning to Xuanhe (1102-1125). It is an extremely important historical document to study the social life, economy and culture of the Northern Song Dynasty, which is similar to the Riverside Scene at Qingming Festival. The picture shows the cover book Shadow of Tokyo Hua Meng Records. According to the book annotation of Tokyo Hua Meng Recorded in China Classic Ancient Books Library, the detailed scene at that time can be better restored. For example, in the article "People Entering the Market at Dawn" in the third volume above, we can see many details of the life of the ancients. "The streets of Zhumenqiao have been opened. For example, there is a child sitting at the door of a soup shop, named' Rao Bone', who has intermittent lung perfusion and lung explosion. " "Rao Gu" here refers to a kind of food mentioned here-"Bufei", and even the detailed methods are written in the annotation of Dream Record in Tokyo. The method of "jade tonifying lung" is to peel real powder, oil cake, sesame and walnut, add a little dill, white sugar and a little red yeast as powder, mix them in a retort, steam them, cut off the lungs and serve them with spicy sauce. In addition, two methods of "Xiangyu Bufei" and "HongLing Meat Enema Bufei" are also recorded, which makes people want to try hand-made. In the sentence "The hotel sells more candles, but it can't tell 20 items, including porridge, rice and snacks", porridge, rice and snacks also have detailed explanations: the porridge here includes: fairy porridge, milk porridge, chrysanthemum seedling porridge, barley porridge, plum porridge, yam porridge and so on. I also wrote detailed practices, such as plum porridge, which is to collect plum petals, cook porridge with snow water until it is cooked, and then roll up the plum petals, so that you can think clearly after eating. "Rice" includes "Yujing rice" and so on. This paper also introduces the noodle restaurant in the book Dream of Liang Lu, which specializes in home cooking, such as bone soup, fish-flavored soup and frozen meat. When it comes to "dim sum", it is much more. You can have a "dish name", stir-fry it, cook it, and everything is complete. The picture shows the homemade yam porridge in "Occasionally, people who sell facial cleanser and fry some soup and tea medicine will make it dawn". In a word, we can find that this magical product called "facial cleanser" was already available in the Song Dynasty. The Annotation of Tokyo Dream is the annotation to it. The facial cleanser sold in the Song Dynasty was doped with medicine, so it was also called "facial cleanser". Imperial Medical Research Institute recorded "Gleditsia sinensis facial cleanser" and "Wax gourd facial cleanser" and so on. From the capital to the palace buildings, from the government to the neighborhood, from eating and drinking to all seasons, from singing and dancing to weddings and funerals, the customs are almost all-encompassing and very rich. By reading and studying Annotations of Tokyo Dream, we entered the world of Tokyo in the Northern Song Dynasty. Screenshot of pc terminal of China Classic Ancient Books Library
