Plenty of wives have tried to poison their husbands over the years, but when Mrs. Zhang decided to take care of her matrimonial problem, she didn't want to go the traditional method of poisoning her husband's food. Instead she soaked her husband's underwear in herbicide before he wore the briefs to his daughter's wedding.
I can't say if Mrs. Zhang wanted to kill her husband or just teach him a lesson, but her husband did survive. Unfortunately for Mr. Zhang, he didn't get treatment until he noticed his genitals were "rotting." He has since recovered from his injuries and no one knows if he yet plans to file charges.
