The Chinese yo-yo, also known as a diabolo, is a traditional Chinese juggling toy consisting of two cups or discs connected by a string. It is spun and balanced on the string using two hand sticks, allowing for various tricks and maneuvers. The diabolo can be made from materials like plastic or wood and comes in different sizes. This toy has a long history in Chinese culture and is often featured in acrobatic performances and festivals. The Chinese yo-yo is not only a source of entertainment but also helps develop hand-eye coordination and fine motor skills in those who practice it.
