In 2015, two grandfathers from China went viral, earning them the nicknames “hottest grandfather” and “muscular grandfather” respectively.

The former was Beijing-based Wang Deshun, then 79, whose toned physique and fierce attitude during his shirtless catwalk during that year’s China Fashion Week took the world by storm. The latter was Guangzhou native Shen Hua, then 81, whose daily one-hour high-intensity strength-training sessions at the gym thoroughly impressed netizens.
