Is there any way to improve feng shui when the house in the countryside is ten centimeters lower than the outside?

Because it's internal.

Be a slave abroad

In feng shui

Weak rule, strong slavery.

The monarch is weak and the minister is strong, and the world is in chaos.

If the master is weak and the slave is strong, the family will scold the father's son.

It's like a husband inside and a woman outside.

Then women take power, and men are powerless.

On health, the inside is yang and the outside is yin.

If yin and yang are not harmonious, all diseases will arise from themselves.

That's unfortunate.
