Does blood donation affect feng shui?

That must be bad. You need to prepare some incense to worship. When worshipping, the things used are whole grains, apples, lettuce, oranges and clear water.

1 prepare whole grains, which means that the grains are abundant and the clothes are safe.

2 Prepare 4 apples, also called Ping An Fruit, which means peace in the four seasons.

3 preparing lettuce means making money.

4 prepare 4 oranges, which means good luck.

Prepare a bowl of clear water, which represents wealth and financial resources.

Prepare a small whip (if not, use fireworks instead) to show prosperity.

Prepare a hammer and knock it three times in the south. It is a shock, which means that unclean things will leave immediately.
