Lao Tzu is the infamous Chinese philosopher who founded philosophical Taoism and is portrayed as a contemporary Confucius. Lao Tzu is a fictional name meaning 'Old Master,' and while he was indeed a historical figure, he was also understood as an embodiment of various philosophers and a deity.
During the Warring States Period, Chinese philosophy was developed to find a solution to violence and establish a moral government. Lao Tzu strived to convince people to accept philosophical Taoism and live a life in harmony coexisting with one another. Eventually, he lived a self-exile life when he concluded that the human race would never listen to his teachings.
