老子 (Laozi) was an ancient Chinese philosopher and writer, traditionally considered the founder of Taoism. He is best known for his work, the Tao Te Ching, which outlines the principles of living in harmony with the Tao, or "the Way." Laozi's teachings emphasize simplicity, humility, and compassion, advocating for a natural and balanced approach to life. Laozi is often depicted as a wise old man, and his ideas have significantly influenced Chinese culture, philosophy, and religion. His thoughts on wu wei, or "non-action," encourage individuals to align with the natural flow of the universe rather than forcefully striving against it.
