This is a traditional type of light which has been used in China for centuries. The light is made by using clay flowerpots which are then filled with oil and a wick.

The use of a flower pot to make the light was considered to be quite ingenious, as it was difficult to make candles or other types of lights that were not easily extinguished.

The invention of the electric bulb has made this type of light less popular, but it still remains an interesting piece of history and culture in China.
