What if the feng shui ball doesn't turn?

Water polo doesn't spin. Wash the cylinder, water polo and birdbath first, and then hide it with clear water. Then check whether the water pipe mouth is sealed. A hose, a lamp. The mouth is sealed with something to prevent water leakage from affecting the ball rotation. After the installation, turn on the power and have a try. Some water can make the ball spin. Most can't. The principle is that all water polo can rotate.
