My grandma was getting older and she had a hard time walking． One day，a doctor advised her to try Tai Chi．

"Tai Chi？" asked my grandma． "Is that a kind of medicine？"

The doctor laughed and replied， " No， it isn't． Tai Chi is a kind of exercise． It is very slow and not difficult to learn． Most importantly， it's very good for your health． "

At first， my grandma didn't want to try it． She said， "I don't feel like exercising． " To help my grandma， our whole family decided to give it a try． We went with my grandma to a Tai Chi class．

Well， it seemed very easy． However， after I tried it， I found it was not easy at all． Even my elder brother Jimmy，the best football player in his school， fell a few times when he was trying to do the action． But my grandma fell in love with Tai Chi at once．

Guess what! Now she goes to the classes three times a week． Although she is almost eighty years old， she doesn't have difficulty walking anymore．
