At midnight, it's the time of the great meeting of Yin and Yang, and the intermingling of water and fire, known as the "convergence of Yin." At this time, the Yin energy is at its heaviest, while the Yang energy has just been born. During this time, the meridians run to the liver and gallbladder, making it the best time to nourish the liver, achieving twice the result with half the effort, so one should be in deep sleep;
Midnight and noon, one is when Yang energy is newly born, the other is when Yin energy is newly born. Regardless of Yin or Yang, both are weak at birth and need good protection. If they are consumed at birth, then their growth, transformation, harvest, and storage become unachievable.
