Yao Ming told at a news conference that a series of foot and leg injuries forced him to end his playing career at the age of 30. "I will formally end my career," said Yao, who became a household name in China before starting his NBA career with the Houston Rockets in 2002. Yao played eight seasons in the NBA. "Today is an important day for me and holds a special meaning for both my basketball career and my future," Yao said. "I had to leave the court since I suffered a stress fracture in my left foot for the third time at the end of last year. My past six months were a painful wait. I have been thinking about my future over and over. Today I am announcing a personal decision, ending my career as a basketball player and officially retire. _  Yao said he would return to work with his former Chinese team, the Shanghai Sharks, with the possibility of becoming general manager. He already owns the club and wants to contribute more. "My playing career started with the club. I hope I can do something for it," Yao said. He later appeared with his family on the stage to the applause and cheers of the crowd. He thanked a lot of people--his family, former coaches, even players like Shaquille O'Neal--"for making me a better player. I will be always with you. Thank you." Rockets general manager Daryl Morey was among those attending the farewell conference. Morey made the long trip from Houston. Morey said 20 hours on plane was tiring but he would be sorry if he wasn't here. "It's a big moment," Morey added. "Yao had a sense of humor, a great attitude and a sense of responsibility. I hope we can continue his culture in the NBA." Which of the following can be the best title of the passage?
