Chinese swimmer Wang Jianjiahe is just 16 years old. But she has already won her first world title. On Dec 14, she won the 800-meter freestyle at the FINA World Swimming Championships, which were held in Hangzhou. She won the race with a time of 8 minutes and 4.35 seconds, becoming the youngest person to win the event. Wang said she still has a long way to go, however. “I won’t stop trying,” she said. She hopes to break her own record next year.
