Laozi was an ancient Chinese philosopher. According to Chinese tradition, Laozi lived in the 6th century BC, however many historians contend that Laozi actually lived in the 4th century BC, which was the period of Hundred Schools of Thought and Warring States Period, while others contend he was a mythical figure. Laozi was credited with writing the seminal Taoist work, the Tao Te Ching, which was originally known as the Laozi. Taishang Laojun was a title for Laozi in the Taoist religion. It refers to One of the Three Pure Ones. Source: Wikipedia.
