I am so happy to know that the promotion campaign for our new product is very successful . We just made a record sale this season .   That is very encouraging news . I heard that the marketing department has done a three months research , they sent the feedback information to the research and development center by the end of every month . That is to say , the R & D center redesigned the product twice before it was launched into the market .   It is not an easy job . How do you like the advertisement for the new product ?   That is the best one I have seen . I am sure our target customers , young people will love it .   Certainly .
