Gong is the pinyin romanization of several distinct Chinese surnames, including 宫, 龔, 共, 公, 鞏, 功, 貢, and 弓.
A member of the Gòng clan, fleeing his troubles, supposedly changed his surname to Gōng by adding the character for dragon (龍) above his original surname (共).
[2] A number of Zhou dynasty royal clans, from the states of Zheng, Wei, Jin, or Chu, had the surname Gong, from which the modern name may be derived.
A number of prominent people named Gong lived near the lower reaches of the Jialing River during the Han dynasty.
The other Gong surnames 共, 龔, 鞏, 功, 貢 have disappeared from Korea.
