A two-year-old girl was rescued after falling into a deep, narrow drainage pit at a construction site in northern China, according to media reports. The toddler accidentally fell while playing at the site in Henan province and was trapped six metres below ground level, according to the People’s Daily . Nearly a dozen firefighters and emergency services staff dug out a six-metre trench to retrieve the girl. The pit she fell into was only 36cm in diameter and had little air. Video footage showed firefighters calling out “give me the oxygen” to other rescue workers as they attempted to retrieve the girl on Saturday. It took about an hour to pull the girl to safety and she was immediately sent to hospital, the report said. No details were given of where in Henan province the accident happened. Internet users in China lauded the rescuers for their efforts in saving the girl, with one writing: “Well done, heroes.” Another commented: “Thank God. Nice work saving the young girl’s’ life!” Chinese toddler who plunged 15 metres into well pulled to safety after dramatic 9-hour rescue There have been numerous instances of children falling down wells in China over the past five years, leading to the deaths of at least 35 youngsters since 2011, according to figures published last year by the Legal Evening News .
