sample:
dear linda，
we haven’t seen each other for six years after graduation. i am so glad to hear that you have graduated from ucla and come back to work in suzhou. if you are free this saturday， please come to shanghai and have a good time with me.
we can first go to the century park， where the flowers are all in blossom. let’s go boating on the lake —isn’t it pleasant in the cool breeze? then i will treat you to dinner at a western restaurant on huaihai road—it is small but really nice—i’m sure you will enjoy it. after dinner， let’s go to a concert—you are a music lover， aren’t you?
if you couldn’t come， please notify me before friday. if you can， please tell me which train you will take and i will meet you at the railway station.
i am looking forward to meeting you.
sincerely yours，
li ming
