What is the meaning of "rushing sheep (Ding Wei) and evil east" in the Yellow Calendar?

This is a term in the "yellow calendar", which means that on this day, people who do things ("appropriate" things in the yellow calendar) will have conflicts with sheep (especially "immature" sheep)-that is, when they meet, things will not go smoothly.

For the same reason, Dongsha means doing what Huang Li said was "appropriate". Generally speaking, there are bad things in the East (Sha Qi), so try to avoid engaging in such activities in the East.
