Archaeological findings suggesting human activity in Hong Kong date back over 30,000 years. Stone tools of the pre-historic people during the old stone age have been excavated in Sai Kung in Wong Tei Tung. The stone tools found in Sai Kung were perhaps from a stone tools making ground. Religious carvings on outlying islands and coastal areas have also been found, possibly related to Che people in Neolithic. The latest findings dating from the Paleolithic suggest that Wong Tei Tung (???) is one of the most ancient settlements in Hong Kong.
