I would very much like to acquire a copy of your January 1990 issue and wonder whether you still have any back copies to sell. Alternatively, I could give you one of my books in exchange, or any other book you might like.
我很希望能購得「光華」一九九○年元月號，不知貴社是否尚有存刊，如果有，可否賣給我一本；如果願意交換，我亦可以贈送一本自己的著作，或者您們所需要的其他書籍。
