Here's more about fast food.

I: What is fast food and the characteristics of fast food:

Fast food is food that is prepared and served quickly in fast food restaurants. Low cost and fast, fast food became popular from the early 20th century.

Fast food is usually hand held and does not require the use of spoons or chopsticks. Fast food may usually be taken out or delivered.

Two: Chinese Fast Food:

Unlike the perception of foreign fast food, Chinese fast food definitely requires chopsticks. At present, domestic fast food is mainly served in disposable fast food boxes and eaten through disposable chopsticks. Chinese people's understanding of fast food is mainly reflected in the word fast. While the production of Chinese food is complicated, fast food does not require consumers to wait for this food production time, and can be eaten directly or simply processed through the microwave oven.

Fast food is in some sense seen as a marker of modern culture, but the fact is that some fast foods may be as old as the cities from which they originate, and the content of fast food varies greatly from culture to culture. In ancient Roman cities there were stalls selling bread and olive oil, whereas in East Asia you are more likely to find pasta stalls. In the Middle East, it might be flatbread and falafel stalls.

Three: Western Fast Food:

The origins of modern fast food are often associated with the burger, as the earliest fast food restaurants used burgers as their main product. The earliest recognized fast food restaurant to open in the United States was White Castle, which appeared in 1921, when a burger cost five cents. White Castle was the originator of the fast food industry and has spawned many competitors.

McDonald's, the world's largest fast-food chain and often associated with fast food, didn't appear until 1948 in the form of a San Diego hot-dog stand, and Ray Kroc, a wholesaler of milkshakes at the time, joined in the creation of the McDonald's restaurants in 1954, when he acquired the rights to distribute them.

The main foreign fast-food restaurants are:

KFC

Pizza Hut

McDonald's

Yoshinoya
