Recently, a foreign blogger filmed many elderly men in a park in Qingdao exercising on fitness equipment. They looked so strong and agile that the blogger couldn't help exclaiming,"Qingdao granddads are training for the Olympics!" It is no secret that Qingdao grandpas love fitness. In recent years, Qingdao's "Chocolate Grandpas" have gone viral online. They go swimming in the sea and exercise on the beach almost every day, and their skin has been tanned "chocolate" by the sun, so netizens call them the "Chocolate Grandpas." Not only do they love sports, but they also have a warm heart. Whenever someone is drowning, they are the first to rush into the sea to rescue the person in danger, and then quietly leave without leaving their names.
