Corduroy, is an ancient lighting device, also known as corduroy, is composed of a core and a thin strip of cloth or paper wrapped around the core. It is widely used in rural and remote areas of China and is one of the main lighting tools for people.

The earliest recorded appearance of the wick can be traced back to ancient China, and it is said that it was first invented by Chinese folk craftsmen. At that time, the wick was called "splendid flower lamp", because people could make different colors of the core into a wick, thus having a colorful lighting effect. However, with the passage of time, the use of wicks gradually changed from home decoration to practical lighting tools.

The production process of the wick is relatively simple, but it requires certain skills. First, you need to choose the right core material, such as cotton or hemp. The core is then wrapped around a thin strip of cloth or paper and held in place with thread. At the end, the made wick is installed on the lamp and the core is lit.

The use of wick is widespread and common. In rural areas, many households still rely on wick as their main lighting tool due to problems with electricity supply. Wick can provide enough light at night to meet the needs of People's Daily life. In addition, the wick is often used as a lighting tool for outdoor camping and wilderness exploration because it is easy to use, portable and affordable.

However, with the development of science and technology and the popularization of electricity supply, the wick has gradually withdrawn from people's lives, and has been replaced by more efficient and convenient lights. Nevertheless, for some residents in remote areas, wick is still their main form of lighting. Although simple, the wick is reliable, does not require a power supply, and is able to provide light in the absence of electricity.

In addition to its usefulness, the wick also has a certain cultural significance. In rural China, it is often used to celebrate festivals and weddings. In these activities, people will decorate the room with colorful wick, creating a warm and warm atmosphere.

In short, as an ancient lighting equipment, although it is gradually replaced by electric light in modern society, it still plays an important role in some remote areas.
