Beijingers lived in Zhoukoudian in ancient Beijing and belonged to Homo erectus. They can use natural fire to make tools (stone tools). For the first time, mankind has gained the ability to dominate a natural force.
People in Beijing use natural fire. The so-called natural fire is not man-made, but thunder hits dry wood and ignites the fire, or volcanic eruption and forest fire. Watch the fire in turn at night. They used ashes to keep the fire. At that time, they baked things with fire and slept by the fire at night, so as to keep warm and drive away wild animals, because wild animals were afraid of fire.

Question:
Zhoukoudian Peking man site has been questioned by some western scholars for 30 years. Due to the lack of evidence of fire, Zhoukoudian ape-man cave is suspected to be a natural "trap" rather than the residence of ancient humans. A press conference was held at Zhoukoudian site, and a large number of newly discovered evidences of "Beijingers" controlling the use of fire were published, which effectively countered the doubts.
A large number of relics show that "Beijingers" learned to use fire 400,000 to 500,000 years ago. There are siliceous bodies in the ashes of the fourth and sixth floors of the Ape Cave, which proves that "Beijingers" used fire, indicating that "Beijingers" used fire in a controlled way on the fourth and sixth floors (400,000-500,000 years ago).
