Though Confucius served the Duke of Lu, a Chinese state, he made many enemies with the nobles of the land. His views antagonized the powerful nobles, who wanted the Duke to be a puppet in their hands. Confucius was exiled from the State of Lu for more than two decades. He lived in the countryside, spreading his teachings.
To rein a kingdom efficiently it is necessary, before all, to put into good order the family. It's impossible for a man who doesn't know how to lead his own family to know how to lead a country.
The determined scholar and the man of virtue will not seek to live at the expense of injuring their virtue. They will even sacrifice their lives to preserve their virtue complete.
There is a growing interest in Confucianism in China and other parts of the world. More and more followers of Confucianism are advocating a deeper study of his philosophies. Confucius' ideals stand true even today. His philosophy on how to be a Junzi or the perfect gentleman is based on the simple ideology of love and tolerance.
