The boy was rescued from the hole in temperatures of -30°C after a passerby heard his whimpers.
Li Qingshu was walking past the public lavatory when he heard the baby crying. Realising the noise was coming from a red plastic bag, he called the emergency services who used a wooden pole to lift the bag out and found the baby inside.
The infant was rushed to hospital in Nenjiang County, north-east China and is recovering well. It is not known who abandoned him in the toilet.
The little boy will be put up for adoption once he is well enough to leave hospital.
Poor little boy, and thank goodness he was found in time.
