How does Feng Shui divide rooms?

In geomantic omen, does housing allocation only start from the children of the deceased or from each generation? For example, my grandmother is buried somewhere and my father is her eldest son. The feng shui master said that my grandmother cares more about my father than the second room. Now that I am my father's second son, does grandma care less about me? Thank you for your explanation. Kneel down and thank you! Fengshui housing distribution is based on children, and grandchildren are divided into grandchildren, which can only be clarified in front of the tomb. Generally speaking, there are many children, and men are left and women are right, with 1, 4,7, 10 on the left, 2,5,8,1in the middle, 3,6,9, 12 on the right. Who is that hill, who is the other hill, and how lucky are they? The mountains and rivers there have been decided and belong to Gankun.
