A man sued organisers after he paid 20,000 yuan (₹2.3 lakh), while being unemployed and in debt, to register for a self-discipline challenge and failed thrice. The challenge required participants to stay in camera-surveilled rooms for 26 days under strict rules, offering a 860,000-yuan (₹1 crore) prize. He was disqualified twice for covering his face for over three seconds.
