"Mobile Phone Broken" tells the story of the old man who can't use a smart phone because he can't see his granddaughter's circle of friends thinking that the phone is broken to repair the phone. After thinking that the mobile phone was broken, the old man took the high-speed rail from the township to the big city alone. When he couldn't find the way, he ran into the high-speed rail staff and was given help. Finally, he arrived at the mobile phone repair shop and reunited with his granddaughter.
