In ancient hotels and restaurants, why did most of them have lids?

Concealment is a trick used by ancient shops in China to attract customers. As a commercial symbol, it is difficult to research at this time, but it appeared in Bianjing (now Kaifeng, Henan) in the Northern Song Dynasty. At that time, in front of some hotels, a piece of red cloth was often hung with bamboo poles, such as "concealment", also called "wine curtain" or "wine flag"

1. The cover is very useful.

For example, scorpions in the cellar hang pumpkin wine on the door; The cover is hung in a circle in front of the door (one circle is made of bamboo or rattan, the other circle is made of cloth and cloth bottom).

2. "Gai" is the evolution of totem worship.

The original meaning of "Sapporo" is the curtain, and then it is related to the wine flag, that is, the wine flag of Du Mu's "Water Village Guo Shan Wine Flag Wind"; The wine flag is also called nine princes when he goes out to show people. "Water Margin" is about drinking down the mountain, and the distance is not very far. "He saw a nine-prince pick it up under the eaves." So some people think that the "hijab" comes from the right or wrong of "babysitting". The hijab originally refers to the wine flag, which can explain why restaurants and restaurants like to insist on using hijab, and it is also easy to remember.

Its origin is mainly related to the weather.

It is very cold in the north. In the past, there were no heaters in the shops. When it is cold, the doors and windows are closed. Customers don't know what's in the shop, so the lid is used as a signal. In the Tang Dynasty, the beverage style prevailed. There is a rectangular cloth hanging in the hotel, and the word "wine" is in the center of the barrel. This is a brewery. In ancient literature, the names of wineries are different, and the most common ones are "Gai" and "Flag-waving".

4. It conveys the banner of political and cultural information;

The shape of the cover is different. The appearance of triangles, diamonds and various physical forms has broken the unique rectangle of fabrics, making the forms of cover announcements more and more colorful. Because different forms of dice advertising have specific meanings and represent different commercial categories of products, e-mail advertising has gradually become a special brand in many industries.
