     Hangzhou, China Millions of Chinese basketball fans who were upset about the retirement of Yao Ming, are excited

tosee another even more shining star, Jeremy Lin, rising from the N.B.A and becoming a popular name all across China.

     "We are amazed by Lin Shuhao's magic performance and should cheer him on," one Internet user wrote.

     "His sport shirts have sold out, even including the counterfeit(仿制品) ones," said Zheng Xiaojun, a 24-year-old

clerk.

     Lin's amazing success over the last month has caught the imagination of the Chinese. He has been particularly

popular here in northern Zhejiang province, from which his grandmother went to Taiwan in the late 1940s.

Jiaxing, a city near Hangzhou where Lin's grandmother grew up.
