《汉书·传·司马相如传下》
大汉的恩德，像源泉一样涌流，泽及遍地，广被四方，像云雾一样散布，上通九天，下流八方。
大汉之德，逢涌原泉，沕谲曼羡，旁魄四塞，云布雾散，上畅九垓，下溯八埏。
The grace of the great Han Dynasty flows like a spring, spreading all over the land, and spreading far and wide like clouds and mist, communicating with the nine heavens above and flowing to the eight directions below.
