Two theories of sheep blade

There is a heavy blade in the yang and a light blade in the yin.

"three cars and one basket" cloud: sheep, say it directly; He who cuts the blade takes the meaning of slaughter. If you go too far, you will be born. If you succeed, you won't give up. That's too much. If a sheep is on the blade, it will get hurt.

Chen Xiyi said: Everything in Yin and Yang is extremely evil. At the extreme, the fire will be extinguished, the water will be exhausted, the gold will be broken, the soil will crack and the wood will be destroyed. Therefore, it is a blessing not to be extreme; If it is extreme, it will be fierce.
