If you insist on geomantic omen, I can only say that the long style of the house has little to do with geomantic omen. As long as you are careful not to make it a special-shaped house, there can be no missing corners. Square, take the meaning of the circle. Then look at the landscape direction next to your home, such as the location of trees, rivers (ponds) and roads. To comprehensively judge the feng shui conditions of the house.
However, I still believe in one sentence: one life, two fortunes, three feng shui, four virtues and five studies. This feng shui is only used as an auxiliary function. Only in this way can we live. As long as you face it frankly, it is the best!
