《史记·七十列传·司马相如列传》
四方邻国都受仁德的教化，南夷与西夷的君长象游鱼聚集，仰面迎向水流，愿意得到汉朝封号的以亿计。
四面风德，二方之君鳞集仰流，原得受号者以亿计。
All the surrounding and neighboring states were transformed by the civilizing influence, and the kings of the southern and western barbarians came swarming like fish, swimming and leaping upstream, eager to receive the insignia of investiture from the Han—numbering in the millions.
