His teammate Meng also joined the rescue effort. Despite the cold water and challenging conditions, they successfully saved both men.
He resides in Beijing with his wife, Xu Feng Yue, who is a former rower. His hobbies include surfing the internet. His wife’s background in rowing adds another layer of athleticism to their household.
His Olympic gold medal remains one of his most memorable achievements. He expressed that winning the Olympics was a dream for every canoeist in China and felt proud to have realised this dream for his country.
After taking a year off following the 2004 Olympics for rest, he resumed training with hopes of competing again for China. He aimed to represent his country once more at future events held in Beijing.
This athlete's journey from swimming to becoming an Olympic champion in canoeing is a testament to his resilience and passion for sports. His story continues to inspire many young athletes across China and beyond.
