Ask Feng Shui master to help me look at the building outside my house. Is it a "corner demon"? The following picture, thank you very much.

You can't count this as a horn demon. For the distinction between horns, please see the following link, which is my previous related answer, "/question/55692125? & Oldq = 1 "

However, the crack between the two floors will form a suffocation and rush into your window, because it seems to be quite close, which has a certain impact. You can put plants on the windowsill to block the suffocation.

But the main cause of your father's illness should be the construction of the opposite building, which is the so-called earth-moving monster, which has a great impact on the health of his family, especially at such a short distance.

You can set up a five-element soil-transforming bureau to crack the earth-moving demon, which was learned from Su Minfeng.

firstly, determine the location of the ground-breaking position. Generally, there are eight possibilities, namely, four corners, and each location has five attributes, as follows: due east-wood, southeast-wood, due south-fire, southwest-soil, due west-gold, northwest-gold, due north-water, and northeast-soil. This is basic common sense, in case you don't know it, popularize it. Then find five things that can represent the attributes of the five elements, such as gold-music box, bronze bell, etc., without sharp gold; Wood-plants can be small; Water-just a glass of water, fire-red cardboard; Earth-small stone.

Then determine the direction of the earth-breaking. For example, if there is an earth-breaking demon in the east, the plants (Oriental genus) will be placed first outside the window on the windowsill where the earth-breaking can be seen, followed by water (aquatic wood), followed by gold (golden raw water), followed by stones (native gold) and finally red cardboard (fire raw soil). This forms a straight line and rushes out of the window, using the mutual strength of the five elements to neutralize the earth. If the window sill space is too small to be placed in a straight line, it can also be surrounded by a circle, but the order can't be wrong. Also, five items in the ground-breaking direction will be placed at the front and rushed out of the window. This bureau can help you solve the problem.

I hope it helps you.

I also hope that it is a doctor's misjudgment after CT confirmation, and even if it is true, I can recover as soon as possible.
