《淮南子·汜论训》
周文王原先处在的岐周一带，土地方圆也不过百里，可是最终立为天子。诸如此类都是因为 得道 和实施 王道 。
文王处岐周之间也，地方不过百里，而立为天子者，有王道也。
The area around Mount Qi where King Wen of Zhou originally lived was no more than a hundred li. But in the end he founded a dynasty. These were all because they obtained the Dao and implemented the Kingly Way.
