The desk faces away from the pool, which is to the west. Some people say this is not very good! How to understand Feng Shui?

Good or bad Feng Shui is relative, not absolute. The desk faces away from the pool. The pool is in the west, which is not particularly bad. Water in the west is good for wealth most of the time. For example, this year and next year will be good. Of course, it would be best if the desk can face the pool to make it more in line with the auspicious Feng Shui pattern.
