Huang Lizhong, what do you mean by herding sheep?

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, things will not go smoothly as soon as they meet.

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