Confucius(孔子) is the greatest teacher in Chinese history. He was born on September 28, 551BC(公元前) in the Kingdom of Lu, in today’s Shandong Province. When he was young, he and his mother had a hard life. At the age of fifteen, he began to learn music, and he did well in it. Then he went on learning other subjects. When he was thirty, he became a teacher. He started his own school. He believed everyone should have a chance to get education whether(无论) they were rich or poor.
