China's veteran of the sea

Editor's note: Guo Zhonghua, 52, a chief engineer of cargo ships working for the COSCO Ocean Shipping (Group) Company, was named one of the top 10 seamen in China last year.

My tanned skin tells people that I am a seaman.

I have worked at sea for the past 34 years, and it took me two decades of training to move from a junior to the chief engineer on board.
