A careless mother accidentally locked her 1-year-old infant in the car. The temperature outside was 30℃. Local residents rushed to the car after the mother had asked for help. One shop owner used a hammer to break the window and saved the child after 15 minutes. The infant was unharmed. It is very dangerous to leave children inside a car. On a 24℃ day, a locked car’s temperature can rise to a deadly 50℃ in 10 minutes.
