這趟行程其實是我在1999年一月，我博士論文口試一個月前，就已經排好的。也因為有如此令人期待的旅程，我也更加努力準備自己的論文。不希望把它搞砸，以免壞了稍後的遊興。事後證明，此趟行程，實在是非常，非常值得的。看了下面的照片，你就會了解的。

I thought after achieving such a big goal in my life, there would not be anything more exciting before the end of this century. But I was wrong...This trip to Peru was so great that I have to call it "The Trip of The Decade"! After looking through those pictures, you will understand why. Wish you were there too!
