What does it mean for relatives of Duke Zhou to jump off a building in costume and land smoothly?

Duke Zhou:

Relatives need help and care. In ancient times, just before. Clothing 1 is decorative 2 defense.

Ancient costume is the lack of care in our life now, and I miss being loved as a child.

Jumping off a building is suicide. Suicide is psychological despair and collapse.

If you land successfully, you will commit suicide but not die, or you will be blessed if you survive.
