Early life and CBA career
Yao Ming is the only child of 6 ft 7 in (2.01 m) Yao Zhiyuan and 6 ft 3 in (1.90 m) Fang Fengdi, both of whom were former professional basketball players. At 11 pounds (5.0 kg), Yao weighed more than twice as much as the average Chinese newborn, and grew to be 5 feet 5 inches (1.65 m) by age ten. At that age, he was examined by sports doctors, who predicted he would grow to 7 feet 3 inches (2.20 m).[7] He began playing basketball at age nine, and went to a junior sports school at the same age.
Yao Ming first tried out for the Shanghai Sharks junior team of the Chinese Basketball Association (CBA) when he was 13 years old, and practiced for 10 hours a day to make the team. After playing with the junior team for four years, Yao joined the senior team of the Sharks at age 17, and averaged 10 points and 8 rebounds a game in his rookie season. However, his next season was cut short when he broke his foot for the second time in his career, which Yao said decreased his jumping ability by four to six inches (10 to 15 cm). The Sharks made the finals of the CBA in Yao’s third season and again the next year, but lost both times to the Bayi Rockets. When Wang Zhizhi left the Bayi Rockets to become the first NBA player from China the following year, the Sharks finally won their first CBA championship. During the playoffs in his final year with Shanghai, Yao averaged 38.9 points and 20.2 rebounds a game, while shooting 76.6% from the field, and made all 21 of his shots during one game in the finals.
