When I was old, I separated my eastern brother from my western brother? Or the elder brother is in front and the younger brother is behind.

Yes, the east is big, so it grows in the east and the west is small. Eat or sit, old people come first, young people come later, and young and old are orderly. This is traditional culture. My old house is in the East Room, my grandparents are in the East Room, my parents are in Westinghouse, and so is my aunt's house. They are in the East Room, and their son and daughter-in-law are in Westinghouse.
