Last year I was the exchange student in the UK, and attended one of the Chinese culture course there. When I walked into the classroom, I was welcomed by curiously faces. They gave me presents, which moved and excited me. The lesson was about an ancient Chinese calligraphy naming xiao zhuan. The teacher explained it origin, how it worked in society, why it was promoted nationwide. After class, I felt proud of our Chinese culture but ashamed of that I knew almost nothing about them. As a senior high school student, I am going to read so many books as I can to open my mind. I hope every Chinese would understand the importance of learning about our own culture.
