How about Feng Shui in U-shaped apartment buildings?

U-shaped and arc-shaped buildings are two different things, and many people regard arc-shaped buildings as U-shaped. The arc may be very mobile, for example, there are many people renting houses, and then the probability of people living there will be higher, for example, the probability of upper respiratory tract infection in children and the elderly will increase significantly. There is a saying that there is a dead house in the U-shaped building, but that is only because the two front ends of the U are very close. In ancient times, U-shaped buildings were generally characterized by small spacing, poor lighting and poor airflow.
