A century-old stone slope bears deep grooves from playful children in eastern China.

The video was filmed in the city of Nanjing in Jiangsu Province on April 28.

Children have been delighting in using the stone slope next to the steps as a "slide". Especially notable are two deep imprints on the stone slope, sparking attention and discussion among visitors.

Some speculate that the grooves on the stone slabs must have been intentionally made by the scenic area to allow children to play.

In response, staff members of the scenic area explained that this "slide" has a history of over 100 years. People have been sliding here for generations, naturally polishing the stone over time.

近日，江苏南京，在朝天宫景区进门处，不少小朋友把这个台阶旁的青石坡道当作了‘滑梯’，玩得不亦乐乎。尤其是青石坡道上有着两道深深的臀印，引起了大家的关注和热议，
有人猜测：“青石板上的凹槽是景区做的吧，方便孩子们玩。”对此，景区工作人员回应称，这个“滑梯”有100多年的历史了，100年前就开始有人在这个地方滑了，算是一代又一代的小朋友，天然打磨而成的。
