Two Neolithic relic sites were recently found in Daqing Oilfield, China's largest oil producer in northeastern Heilongjiang Province, pushing back the local civilization history to 3,500 years ago.

Zhang Shaojie, director of the Daqing Relic Protection Station, said that archeologists have unearthed large amounts of stone-head arrows, stone-cut tools and articles made of animal bones, which carry typical Neolithic characteristics.

One of the stone-head arrows is finely made and still sharp. Archeologists also found arrow heads made of white agate.

Both of the archeological sites are located by the riverside. Experts have ascertained that ancient residents had lived a primal fishing and hunting life.

The Neolithic relic sites were found when archeologists made an emergent excavation of an ancient tomb which belonged to the Liao Dynasty over 1,000 years ago.

The oil reserve of Daqing was tapped in 1950s, before which the place was a deserted alkaline land.
