These days, videos of “diving (跳水) grandpas” from north China’s Tianjin are popular on the Internet. In the videos, they jumped off the Shizilin Bridge into the 7-meter-deep Haihe River. However, on Wednesday, they announced that they would give up the sport.

With an average age of 60, the diving grandpas have much experience in diving. They started as a group of local diving lovers. They went swimming in the city’s rivers, and later they tried their hand at diving. The hobby has now lasted for more than thirty years.

Videos on the Internet have drawn lots of tourists from across the country to the Shizilin Bridge over the Haihe River, where “diving grandpas” perform diving. However, some inexperienced divers, in trying to emulate “diving grandpas”, have met with accidents and got themselves injured. Some of the grandpas have begun volunteering to keep order for the crowds that come to see the performance on the bridge.

The grandpas then made a difficult decision. They stopped diving off the bridge. They also prevented inexperienced locals and children as well as tourists to dive from the bridge. The grandpas welcomed the tourists to Tianjin, especially pointing out the other great places of interest and delicious food around the Shizilin Bridge. 

With the weather in the city turning colder, the grandpas said they will start looking for safer public locations to continue their hobbies.
