Dear Mr. White,

I'm Chen Hui, one of Mr. Smith's students.Learning that a part-time waiter is needed in your coffee bar, I strongly recommend Wang Lin, one of my best friends, for the post.

I believe that Wang Lin is qualified for the job.First of all, his spoken English is fluent, which is one of his big advantages. As regards his personality, he is honest, responsible and cooperative. In addition,whatever work he does, he always takes it seriously.He is characteristically punctual, careful, effcient andabove all, patient. I'm convinced that once employed,he will live up to your expectations.

Therefore, I highly recommend Wang Lin to you.Should you need more information concerning him,please do let me know.

Yours,

Chen Hui
