Dear Tom,

I’m glad to know you are crazy about traditional Chinese medical science but eager to study it following an expert. I’d like to recommend Mr. Zhang like your teacher. Mr. Zhang is professor in this field. He often gives medical care to people who have healthy problems. So you can turn to him and to learn medical knowledge from him.

Yours,

Lily
