A night runner called Mr Chan vaguely heard some voice crying for help, he search around warily, and found the source at last. It was from an abandoned water well. It looked so deep, Mr Chan called 110 and 119 for help at once, and explained that a child had fallen into a deep well.
The fire prevention guards came with the police very soon. They made a rescue plan.
The well was very narrow, so the fireman could not watch downward clearly. Fortunately, they had purchased a set of borehole camera from TLS Technologies Company two months ago, so by using the camera to help to inspect the well, the commander could conduct the fireman properly. Twenty minutes later, the poor boy was saved.
