A young woman cooked a meal at home for her hearing-impaired father, who was dozens of kilometers away. A Dingdong delivery worker who helped deliver groceries to her family refused to accept any payment. In gratitude, she topped up his phone credit with 200 yuan. Dingdong later rewarded the worker with 2,000 yuan in cash. The woman shared this story online, but instead of appreciation, she was cyberbullied by countless netizens who criticized her for tipping "too little." Unable to bear the pressure, she ultimately took her own life by jumping from a building.
