If you don't want to make a ceiling when decorating, wouldn't it be nice to have a beam on the door or a beam on the table (as shown below)? Are there any taboos?

I think, in ancient times, the beams above could be hidden by Tibetans, thieves could be on them, and killers could be hidden on them. If people sitting under or on the bed have this thing, they will put themselves in danger, so those feng shui masters who have seen the light sum up their experience and had better not cross the beam to top it. As for whether this is the case, there is no way to verify it.

As far as modern cement beams are concerned, if there is a beam on the sofa or bed in terms of ventilation, the wind will blow on the head, and then it will cause headaches for a long time.

So now, to solve the problem of smooth wind direction, we can find ways to enlarge the beam, that is, to make a small ceiling, whether it is an arc semi-enclosed or flat roof, which can solve the ventilation problem. But personally, I think it's a bit exaggerated. That little romance is just theoretical. Even if nothing is done, it will not really affect people. Science can be proved by examples, and Feng Shui must also prove itself by examples.
