If it is possible， please go downstairs to help me to get it and put in into our dormitory tomorrow.  　　</p><p>By the way， as you are really interested in Chinese history， I have boughtyou a book about Tang Dynasty online as a birthday gift. If you want to have a good command of Chinese history， you can&rsquo;t miss it. I hope you will be fond of it.</p><p>Yours，  　　</p><p>Li Hua</p>');
