Can I hang a mirror at the end of the corridor? Does it affect feng shui?

No, the long segment itself will produce suffocation, which is easy to understand. Deep and long alleys can make people feel scared, right? The alley in the design is not long and the suffocation is not heavy, but adding a mirror to double the length of the passage will increase the suffocation. In the long run, it will affect people who are weak. It can be installed, but it is not necessary.
