Translation for Traditional Chinese Wisdom
1. Benevolent people see all things under heaven and themselves as one.
（Writings of the Cheng Brothers）
2. He who acts according to the seasons and the nature of the land will enjoy great success without much effort; those who act arbitrarily and violate the natural laws will gain nothing in the end.
（Qimin Yaoshu）
