范文：預(yù)先告之對(duì)方方便聯(lián)系的時(shí)間

I am at present in Hamburg visiting the harbour with a view to making known our new type of container for use in Europe.

I shall be in Antwerp on Wednesday, 4th June, and should like to call on you at 2.00 p.m. on that day.

If I do not hear from you to the contrary, I shall assume that it will be convenient for me to call at that time.

Yours faithfully
