Brian : I know I sound like a hypocrite on this matter, I didn't mean they should stay in slavery.

Man in China passed from primitive society to slave society in the 21st century B.C., with the founding of China's first dynasty, that of the Xia.

But to return.I have shown that no society of slaves can endure, because, in its very nature, such society must annul the law of development.

This era was followed by the Spring and Autumn and Warring States periods (770-221 B.C.), marking the transition from the slave society to feudal society.

It was marvelous for Confucius to propose such a great thought at the later time of Chinese slavery, it set a basis for the national development and harmony.
