In order to save a dog, the High Bridge Fire Department in the East District of Shanghai launched three successive operations to rescue the dog, especially for the purpose of drilling the pits (human holes) and climbing the dung pits to regenerate the stray dog who was trapped overnight.

According to the New People ' s Evening newspaper, at almost 11 p.m. on the late 19th night, the fire squadron at the High Bridge in Pudong New District sounded the alarm, and the alarmist alleged that dogs had been heard in the sewer but could not see them. Firefighters arrived and the screams disappeared, and in the night, the search was fruitless and the rescue was rendered useless. The police said the dog had a master.
The following morning, firefighters were again ordered to find helpless dogs in a sewer. The dog's position is approximately half a metre from the guillotine pit, which contains water. The firefighters didn't think much, either, but they went in and watched the dog. The flashlight was on, the dog was pathetic, and it could drill through a hole in the head, but the body could not pass.
