The reward itself, such as material rewards or spiritual encouragement, is not directly related to the traditional Chinese medicine concept of kidney deficiency.
2. Kidney deficiency is a concept in traditional Chinese medicine theory, usually referring to insufficient or imbalanced kidney function, which may be caused by various factors such as overwork, irregular diet, emotional disorders, etc., but has no direct causal relationship with the amount of external rewards.
If "reward" is understood as some kind of excessive behavior, long-term excessive behavior may lead to physical fatigue, increased mental stress, and indirectly affect physical health, including possibly affecting kidney function. But the 'kidney deficiency' in this situation is not directly caused by rewards, but by an imbalance in physical state caused by excessive behavior.
