【正确答案】Dear Mr. Smith, I am Li Jun, the assistant manager of marketing department. I’d like to report to you our market investigation and customer feedback. In recent days, members of marketing department visited some clients and listened to their opinions and suggestions on our products and services. In general, they are satisfied with our products and services we offered. However, clients also pointed out some problems we had. They suggested we should enrich our products by offering fashionable ones, and offer some training (on product use) so that they can use our new products easily and effectively. In the end, the market investigation will be attached so that you can know our customers’ attitude to our products. Best wishes! Yours sincerely, Li Jun
