Kong Zi (Confucius), the historical Chinese saint, is considered to be the greatest teacher of China.
His teacher was Lao Tzu (Laozi). Kong Zi said that Lao Tzu was a dragon who hid in the clouds. He learned from Lao Tzu all his life but could not understand all his great wisdom.
2,500 years later his work has been translated into many foreign languages. Lao Tzu believed that people should learn from nature and keep a harmonious relationship with nature.
Beside a river, Lao Tzu told Kong Zi that a saint should act like flowing water. Water gives life to others but does not fight with others. A saint makes no error and no one hates him. Therefore, he can make great achievements. In China, Lao Tzu is considered the elite of teachers.
