Wang Jinxi or Wang Chin-hsi was a Chinese model worker and socialist hero known as 'Iron man' Wang, who led No. 1205 drilling team at Daqing Oil Field.

The Daqing Oil Field, formerly romanized as "Taching", is the largest oil field in the People's Republic of China, located between the Songhua river and Nen River in Heilongjiang province. When the Chinese government began to use pinyin for romanization, the field's name became known as Daqing.
