Wei Liqin, 34, was attacked in Dongguan, Guangdong province, in 2011 - though he cannot remember any details of the attack due to the head injuries he sustained.
When he woke up in hospital, doctors told him they had removed part of his skull to relieve the pressure on his brain.
Wei says his injury still causes him pain
Unfortunately, with no money for further treatment, Wei had to leave hospital with part of his skull still missing.
Wei says his injury still hurts, and he has to be very careful day-to-day as the right part of his brain is only protected by a thin layer of skin.
An artificial skull piece will cost him 40,000 yuan, which is about £4000 in pounds. Wei and his family are now attempting to raise money so that he can have the operation.
