What is the origin of candles?

Candles have a history of more than 1000 years in China. Nowadays, in the case of extremely rich electric light sources, candles with a thousand-year history still exist and develop with their tenacious vitality, which is an interesting thing. It is said that the earliest candles were made of butter, that is, butter was used as raw material and reed sticks were used as the core to roll cotton paper to make butter candles. Later, with the discovery of paraffin wax, candles were made of wax. Since then, paraffin has replaced butter and cotton has replaced reed. Today, candles are still an indispensable necessity in people's lives. In many places, candles are used to set off the holiday atmosphere, especially the traditional festival in China-Spring Festival.
