How to see the house lacking corners and protrusions

Mr. Huang of Nanjing asked:

See a sentence from the Internet:

There is no distinction between old and young in the yellow vagina, and it is terrible to lead the way with a bull's-head face. The balcony on the south side of my house protrudes from the room. Please ask Dr. Zheng to help me see if it is fierce.

Dr Zheng Weijian replied:

1, lack of angle and protrusion are interrelated.

Dr. Zheng has published several articles on the problem of convex rooms with missing corners. In fact, lack of angle and prominence are interrelated and must be treated dialectically. But to make a correct judgment, it requires us not only to have a solid basic knowledge of geomantic omen, but also to have corresponding professional tools to assist measurement, so as to make a correct analysis and judgment. 2. The problems in the room should be judged as a whole.
