As soon as Xiaomei ran out, grandma suddenly collapsed, angered into unconsciousness by Xiaomei's unfilial behaviour. The family rushed to support her, fortunately her sister-in-law was close by, so grandma didn't fall directly to the ground.
They called for a doctor who, after examination, said it was a case of anger attacking the heart and recommended calming therapy. She needed rest and to avoid further agitation, else she could have a stroke.
