Liu Fei, Prince of Jiangdu

Liu Fei's mausoleum has been excavated by archaeologists from the Nanjing Museum, who unearthed numerous artifacts, including 100,000 coins, dozens of chariots, and the only jade coffin to have survived intact in Chinese archaeology.

[2][3] In 154 BCE, rulers of seven kingdoms, led by Liu Pi, the King of Wu, rebelled against the Han dynasty.

Emperor Jing awarded him the seal of the general, and let him lead an army to attack Wu, the main rebel kingdom.

[2][3] The following year, Emperor Jing created the kingdom of Jiangdu in part of the former territory of Wu and made Liu Fei its king.

[2] According to the Han historian Sima Qian, Liu Fei built many palaces and towers, and his life "was marked by extreme arrogance and luxury".

[4] Although the site has been looted in ancient times, archaeologists still unearthed more than ten thousand artifacts: gold, bronze vessels, weapons, a zither with jade pegs, lamps of various shapes, a silver basin inscribed with the name of the Kingdom of Jiangdu, and a kitchen with food.

[4] Liu Fei's coffins were damaged and his body was missing, but fragments of his jade burial suit were found.

The most important find was from an adjacent tomb, labeled M2, which contained the only jade coffin known to have survived intact in China.
