Thirty-year-old Sanda national champion Zhang Zhijun knocked out 40-year-old veteran Lei Fujiang to the ground with a backhand punch in the last two seconds of his title defense. When he raised the gold belt, no one knew the person who fell. His daughter was in the ICU waiting for a bone marrow transplant, his wife ran away, and his old mother was waiting at home to take medicine. After Zhang Zhijun learned the truth, he quit the ring, spent twelve years of savings, sold his house, and gained a life and the continuation of a family.
Two years later, when Lei Fujiang stood up again, he made a decision - to be a sparring partner for his former enemy. Because he knew better than anyone else that the fire in this young man's heart had burned out and someone needed to relight it for him.
