The term means that one should strive continuously to strengthen himself. Ancient Chinese believed that heavenly bodies move in accordance with their own nature in a vigorous and forever forward-going cycle. A man of virtue, who follows the law of heaven, should be fully motivated and work diligently to strengthen himself. This is the Chinese view on governance and self development, established with reference to the movement of heavenly bodies. Together with the notion that a true gentleman has ample virtue and carries all things, it constitutes the fundamental trait of the Chinese nation.
