《老子·德经·第五十四章》
所以以自身的修身之道来观察他人，以自家观察他家，以自乡观察他乡，以自己的国家观察其他的国家，以自己的天下观察别人的天下。
故以身观身，以家观家，以乡观乡，以邦观邦，以天下观天下。
Therefore, observe others with their own way of self-cultivation, observe others' families, and observe other townships with their own townships, observe other countries with their own countries, and observe others with their own world.
