It was the bear child who played with fireworks again, threw the fireworks into the sewer, and as a result ignited the biogas in the sewer, the manhole cover and the ground were blown away in an instant, and the child cried and ran to find his mother, and the parents were also frightened. Fortunately, the child was only frightened and not injured. This is no longer a case, every year watching the news will see children throw fireworks into the sewers caused by accidents and bloody cases, I hope that parents will take this as a warning, when the children set off fireworks and firecrackers, we must warn children not to throw firecrackers into the sewers, otherwise it is really regrettable!
