These seven things, such as firewood, rice, oil, salt, sauce, vinegar and tea, are the seven things that ordinary people in ancient China ran about for their lives every day, which has become a proverb in China. From the beginning of "opening the door" (that is, a family begins to run normally in a day or manage a family to make a living), it is inseparable from seven necessities to maintain daily life, namely: firewood, rice, oil, salt (salt), sauce, vinegar and tea. Seven things to remind families of various necessities. The theory of seven things opening the door is generally believed to have begun in the Song Dynasty. Seven things were new to people at that time. Rice (that is, paddy) was the main grain in Song Dynasty. Sauce only refers to soy sauce in the Song Dynasty. Before the Song Dynasty, vinegar was not a necessity. Tea was a luxury in the Tang Dynasty and even the Northern Song Dynasty, and it was not common. As for oil, it refers to the oil squeezed from sesame, perilla and hemp, which was popularized in the Southern Song Dynasty due to the development of handicraft industry and commerce. Many literati's songs are based on seven things to open the door and exist in the folk. The arrangement and contents of the seven activities are very particular, and they are all related to the long-standing food culture in China. Today, the significance of the seven things to open the door is different from that in ancient times, mainly referring to the essential things that have vital interests with the people. When the proverb "seven things to open the door" began remains to be verified. In the Southern Song Dynasty, Wu mentioned eight things in Meng Lianglu: firewood, rice, oil, salt, wine, sauce, vinegar and tea. Because wine is not a necessity, it was eliminated by the Yuan Dynasty, leaving only "seven things". The seven things of opening the door appeared in the spoken language of Song Dynasty at the latest. Therefore, it is generally believed that Wu is the person who created the seven images. According to the book Story of the Lake and the Sea in the Yuan Dynasty, there was a saying in the Song Dynasty: "The lake girls are gorgeous and charming, and they are eaten by people on weekdays. Tortoise hesitates, that's what pious women do! Seven things to do in the morning, soy sauce, soy sauce, ginger and pepper tea, and silk in winter and summer. Didn't you see that Zhangbazi in Huzhou sold 10 million hectares of fertile land, but now he is fishing for frogs, and his knees can't cover him! " In addition, seven things, such as Yuhuchun, Duliucui and Baihua Pavilion, were also mentioned in Yuan Zaju. Among them, the "seven things" are "Liu Xingshou": "Teach you to be a master, not to be a master, until you are in a mess; Seven things to open the door early, rice, oil, salt, sauce and vinegar tea. " From this, it shows the "seven things" that the master has worked hard all his life. In the Ming Dynasty, Tang Bohu pointed out these "seven things" with a "New Year's Eve": "All the rice, oil, salt, sauce, vinegar and tea are in other people's homes; There is nothing to do in the twilight, and I wish the Tang Temple to see plum blossoms. " With the progress of society and the continuous improvement of people's living standards, seven things have also made progress. In most areas of modern China, firewood has been replaced by liquefied petroleum gas, natural gas and gas. Rice, oil, salt, sauce and vinegar are still the main components of China's food culture; As for Chaze, it is famous for its unique tea culture. On the other hand, the time of life is not as good as before. In the past, seven things took up quite a lot of time, but now it is getting easier and easier to get and deal with them.
