CHENGDU, Nov. 9 (Xinhua) -- Wang Qichang, 88, is a famous high-speed railway expert in China.
Since his graduation from college in 1958, Wang has been devoting all his life in teaching and scientific research. In his words, all his work is about innovation. "I just want to find the most urgent areas to study, break through the most critical bottlenecks, and follow up the most cutting-edge issues," he said.

In the year of 2012, Wang, who is about 80 years old, began to focus on sound barrier technology along the high speed railway, which at that time is a gap in China.
After three years of hard work, Wang and his team overcame numerous technical difficulties and finally got success. The evaluation results showed that its key technologies reached the international leading level.
