What is the meaning of "Zhengchong Zhengchong Wuwu" in the Yellow Calendar?

The forward thrust is in the position of hedging, and there are six forward thrust positions in the twelve branches. For example, there are six pairs: Zi and Wu, Ugliness and Wei, Yin and Shen, Mao and You, Chen and Xu, Si and Hai. There is no hedging for ten days' work, only mutual restraint. Hedging is much heavier than xiangke! If the third son fails, his life may be over.
