<Oh! Click> The second search term is'raised manhole cover'.
This is Dazhou City, Sichuan Province, China. It is a plaza where many people come and go.
Suddenly the manhole exploded.
Three manhole covers rose into the sky with a roaring sound at once, and white smoke came out from the sewers, covering the square.
People who are surprised are evacuated in a hurry.
Anyone who did this dangerous thing was captured by CCTV.
Looking at the CCTV, we could see that a child dressed in white like this puts a firecracker through a hole in the manhole cover and hurriedly avoids himself.
Three manholes exploded in no time as the sparks of the firecracker he put in them met methane gas in the sewer.
However, in China, accidents related to firecrackers are repeated every year.
In China, firecrackers mean that they chase ghosts and bring good luck. Especially, during the Chinese New Year, the biggest holiday in China, the custom of enjoying firecrackers continues to cause accidents.
Netizens who saw this said, "The manhole explosive power is so strong... Let's never imitate it!" "You don't just look at the pretty firecrackers, there are different ways to buy and play!!" And so on.
