Ladies and gentlemen,

    Thank you for hold such a wonderful party for me before the day of your returning to Australia. I really can't thank you enough for that you've done for me during my visit.

    I remembered vividly the day I arrive here. I was deeply impressed by your kindness or the beautiful scenery of your city. Everything was more awesome than visiting the splendid Mount Huang on third day. And the memory will surely last a lifetime. I'm also glad to have made many friends here, to whom I hope to see again in the future.

    I believe this visit will promote the friendship and understanding between the Australian and Chinese student. Once again , I want to extend my most sincerely gratitude to all of you.

Thank you.
