Is the blood of ordinary people in Feng Shui good?

In fact, there is no special emphasis on blood donation in Feng Shui. Of course, there was no such technology or thing as blood donation before.

In fact, from the perspective of yin and yang, it is not good for people with weak constitution to donate blood, because it hurts their vitality, and it is no problem for healthy ordinary people to donate blood.

Good luck! This is a good thing!
