The work is honorifically known as the
Taishang lingbao Laozi huahu miaojing (, "The Supreme Numinous Treasure's Sublime Classic on Laozi's Conversion of the Barbarians"). Traditionally, it is said that
Laozi wrote it with the intention of converting
Buddhists to
Taoism, when they began to cross over from
India. The Taoists are sometimes claimed to have developed the
Huahujing to support one of their favourite arguments against the Buddhists: that after leaving
China to the West,
Laozi had travelled as far as
India, where he had converted—or even become—the
Buddha and thus
Buddhism had been created as a somewhat distorted
offshoot of Taoism. Some scholars believe it is a forgery because there are no historical references to it until the early 4th century CE. It has been suggested that the
Taoist () may have originally compiled the
Huahujing circa 300 CE. ==Destruction of copies==
