糖吃多了牙会疼牙吃多了糖会疼
[táng chī duō le yá huì téng yá chī duō le táng huì téng]
This interesting phrase means 'Too much candy hurts the teeth, just as too many bites hurt if the object of bite is reversed'. It carries a sense of balance in life; indulging excessively in sweetness might cause pain, literally and figuratively.
