Candles have a history of more than a thousand years in our country. Today, when electric light sources are extremely abundant, it is an interesting thing that candles with a history of thousands of years still exist and develop with their tenacious vitality. It is said that the earliest candles were made from butter. They used butter as raw material and rolled tissue paper on a reed stick to make a butter candle. Later, with the discovery of paraffin, wax began to be used as candles. Since then, paraffin has replaced butter, and cotton core has replaced reed. To this day, candles are still an indispensable necessity in people's lives. During every festive season, many places have the habit of using candles to heighten the festive atmosphere, especially my country's traditional festival - the Spring Festival.
