The ancients mainly used wax for lighting, but also used Songming (pine wood rich in oil, called Songming after lighting), tung oil, cattle, and sheep oil. Beeswax is mainly used in pharmaceuticals. Wax for lighting can be obtained in a more economical and simple way, which was the case until the middle of the last century. I have witnessed it with my own eyes, so I know it. The method is: there is a kind of tree called "Chinese tallow", its seeds are rich in wax. Every autumn, when the seeds of Chinese tallow are ripe, a large number of people are collected and boiled with water, which is easy to obtain.1
