You may not choose to pursue yo-yo as a career, but you may choose to integrate yo-yo into your daily life. After study and work, put down the heavy burden on your heart for a while, take out a beautiful yo-yo ball and play it for a few times. It can not only give the eyes that have been tired from reading books and computer screens for a long time a temporary rest, but also make the fingers that are stiff because of holding pens for writing and tapping the keyboard for a long time. Why not?
