CCTV footage captured the moment the deadly blast went off at a grilled fish restaurant in Gaomi, in Shandong Province at around 7:15am on 13th August.
The video shows vehicles travelling as normal when suddenly thick smoke spews from the side of the street.
A powerful shockwave carries debris from the shattered building materials and it even knocks a passing car sideways.
Another piece of footage shows a white sedan looking severely damaged, with the driver’s side door open and visible cracks at the rear of the car.
A man is seen sitting on the ground, leaning against the car after apparently being injured.
Another injured person is seen lying in the middle of the road which is covered in debris.
The windows of the restaurant and a nearby bank have all shattered, and the ground is littered with bricks, tables, chairs, and other debris.
Rescuers later arrived and saved two people, Chinese media reported.
But two others were killed in the sudden gas explosion.
It is unclear what caused the deadly blast.
The victims have not been named in local media.
The incident comes after a nationwide campaign announced by Chinese leader Xi Jinping in June after more than 30 people were killed in cooking gas explosion at a barbecue restaurant in the city of Yinchuan.
The investigation is ongoing.
