Globetrotting couple sketch their travels

Chen Zuchang has a different way of documenting his travels - instead of taking pictures, he sketches the places he visits.

The 77-year-old retired engineer from Chongqing in Southwest China has drawn more than 100 pictures of the cities and countries he has visited since his retirement.

In 2015, together with his wife Luo Xiansui, also 77, Chen went on an 86-day around-the-world cruise, stopping off at 18 countries and regions in the Northern Hemisphere. The trip cost them 148,000 yuan ($21,600) each.
