Rainer Hirsch, Managing Director of Guangzhou Herrenknecht Tunnelling Machinery Co.,Ltd., has worked and lived in Guangzhou for over 20 years. When talking about the city, the first thing he mentions is what lies underground—from the Haizhu Bay Tunnel to metro lines, he has witnessed Guangzhou's underground engineering and urban construction grow better and better.

"Over the years, Guangzhou's tunnelling projects have kept breaking through technical challenges. Our technology has taken root here and, step by step, reached the global market."
