Fu Chieh-tzu (1st Century BC) was a commander under the Emperor Zhao of Han dynasty. He killed An-kuei, the ruler of Loulan in 77 BCE.
Although fond of study, at fourteen years of age he threw his writing-tablets aside, saying with a sigh, “Tis in foreign lands that a hero must seek renown; how can I let my life pass away as an old bookworm?” At that time the rulers of the Kuei-tzu and Loulan countries had killed some Chinese envoys; and with a view to punishing them, Fu volunteered to proceed as envoy to Ferghana or Khokand. As a result of his mission, in 77 BCE, he slew An-kuei, the ruler of Loulan;[1] and when he was asked for some proof of his statements, he produced the monarch’s head.[2]
