My ambassadorial duties will include introducing British visitors to the 120-plus pandas at Chengdu and others at a research centre in the misty mountains of Bifengxia.

Yesterday we went camping at the foot of the mountain. What impressed most was the beauty of the high mountain. There were a great many tourists visiting the mountain. There was no doubt that they were attracted by the beauty of the mountain as well. During the camp, we found some waste thrown away by the tourists. What we were concerned about was whether the tourist spot could be well reserved.

When I was a university student, I was attracted by the Chinese. So I got a job as a teacher in Wuhan three years ago. Thinking back, I realize it was the students I met in the first year and Chinese university life in general that gave me the deepest impression.

During my schooldays, I would rarely give up my spare time to any activity connected with study. Unless exams were approaching, my weekends were devoted to having fun or perhaps a part-time job. My Chinese classmates, on the other hand, seemed to spend their entire waking hours studying. I understand that competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put me to shame.

My first year in China was also my first year as a teacher. It was both challenging and rewarding. One thing I know for certain is that my year in Wuhan helped me change for the better. Thanks to the politeness and warmth of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most importantly, I met dozens of nice people and made many excellent friends.
