Grey-haired Chang Zhifu stands out from the young volunteers working   guides in Xidan Culture Square, one of the capital city’s booming business districts.
“Welcome to Beijing. I am an Olympic volunteer,” Chang said on Tuesday to Carhen Winston,  _ tourist from Washington D.C.
“It’s  (amaze) to meet a 66-year-old Chinese lady    speaks good English,” Winston said.
In order to become a volunteer for the Beijing Olympics, Chang began to study English and sign language a year ago.
“As an old Chinese saying   (go), ‘It’s never too old    (learn),’ and    I have to do is to put in more efforts,” said Chang.
Every day she carries two booklets, one for English and the other for sign language. The time she spends _ the bus is “always good for revising”.
Chang   (invite) to teach sign language to young volunteers now and then. “Go, China!” is always the first sign she teaches.
“Granny Chang is quite a celebrity here, because of    hard work and Olympic spirit. We just want her to have a short break.” Wang Hao, the leader of the volunteer team said.
