Xu Baokun never thought that one day she would become popular on the Internet.Her videos on Douyin have recently got a lot of"likes".with people calling her"Cool Grandma".In her videos，Xu plays the drums very well.Xu，now 67，lives in Guangxi.For many years，she has worked hard as a farmer.Things，however，changed last year when her son brought home a drum set.
At first，Xu saw the drum set as a noisy novelty （新奇事物）.But after she watched her son's shows several times，she became interested in it.Since then，she has tried her best to teach herself by watching the videos online.
With lots of practice，her skills have improved greatly."It's never too late to learn，"Xu said."I'll continue to improve myself by learning more difficult music."
