A man in his late 50s divorced his innocent wife after his B blood type was wrongly recorded as O at odds with their daughter's.

    Liu was told he had type-O blood after donating in Daqing, Heilongjiang province, in 1999.

    The mistake was only discovered years later when, recording all his family members' blood types, he found his daughter's was type B and not O like his and his wife's.

    Suspecting her of falling pregnant to another man, he divorced her.

    But later his B type was confirmed in another hospital.

    "I'm going to sue the blood donation center," he said.
