在国内很畅销、实用性强，或国外可能有需求的物品，都应该积极开拓销路。甚至在国内不畅销的东西，有时在国外却有意想不到的需求。总之，确切掌握资料是商业上的重要的工作。

Dear Sirs,

You will be interested to hear that we have recently developed our new product, which is selling very strongly on the home market.

Because of its success in Taiwan, we thought there might be a sales potential abroad, and we would welcome your advice as to whether, in your opinion, there is a market in your district.
   
If you agree we shall be glad to supply you with samples for you to show to potential customers. You will find enclosed an order form in case you wish to make an immediate order.

Yours  faithfully,
