1. Look at the appearance: the surface of the ball is clean and non-reflective, and the waist of the ball is clean and clean.
2. Test bounce: the ball should be released several times at the same height, and the ball's first bounce should be consistent.
3. Hardness: knead the top of the ball with the thumb and forefinger (the LOGO is facing itself, the top is the top) and the soft hardness should be consistent.
4. Roundness and center of gravity: table tennis balls should be rotated on smooth, flat surfaces without violent vibration.
