What does the four-faced Buddha in Mengling Buddha in Xishuangbanna mean?

Four-faced Buddha is a common name for Brahma in China. "Brahma" is also known as the day of making books, Brahma and the day of purity in Buddhism. Brahma, one of the three main gods of Brahmanism, is the god who created the universe. In Southeast Asia, especially Thailand, it is considered to be a god with infinite magic and wealth in the world; Its four sides face the southeast and northwest respectively for believers to pray. Because the shape is similar to that of the Buddha in China, Chinese translation is mostly four-faced Buddha, but in fact, four-faced Buddha is not a Buddha, so it should be accurately translated into four-faced god.
