Hi Jiang Ming,
How wonderful to hear that you have finally decided to pay me a visit during your summer vacation. My family and I would most welcome you to Beijing.
But since you will be coming during the busy holiday season that you might find it hard to buy your travel ticket, so make sure that you book it a little earlier to avoid problems.
I shall take you visiting many of our famous landmarks here in Beijing during your stay, sucha as the Summer Palace, the Forbiden City, the Thirteen Tombs of the Ming Dynasty, the Great wall and of course Beijing Univeristy too.
Before you set off, would you be kind enough to give a ring first to tell me your date of travel and time of your train's arrival, so that I know when to pick you up from the station. In the meantime, please keep in touch. A best friend of yours, Li hua.
很乐意能够帮到你,希望会对你有助.
若不明白请继续问,如满意敬请采纳,O(∩_∩)O谢谢你.
