留侯世家

张良 was made Marquis of Liu for his service to 刘邦, hence the title. The chapter tells how he hired a strongman to strike at the First Emperor with an iron hammer, how an old man on a bridge, later known as 黄石公, gave him a book of strategy after testing his patience, and how the emperor praised him for planning in his tent the victories won a thousand li away.

Sima Qian kept 世家 'hereditary houses' mostly for the ruling families of the old states, but also gave the title to Confucius, to the rebel Chen She and to a few founding ministers of the Han whose fiefs passed to their heirs, Zhang Liang among them.
