How to determine the center point if the shape of the house in Yangzhai geomantic omen is irregular? As shown below, can the kitchen be repaired only after it is demolished?

A house with good feng shui adheres to the principle of "steady and steady", but it is rare for such a house to have many yin and yang angles. Resolution should be the first choice, and it can't make up for the missing angle.

Why do you say that the central line should be demolished and the kitchen is repairing it? I think we should calculate the center point of the cross again in the square (see red line).
