It’s not enough for you to just talk like this. In addition, I don’t recommend that you look for answers in this regard online.
To look at Feng Shui, you must at least provide a floor plan (regional plan and local plan), the history of the current building, the purpose of improvement, the surrounding businesses, and the basic situation of the boss. This is your early preparation.
Next, you have to choose which Feng Shui method to use to improve it. If the changes are not major, it is recommended to use Qingwu Feng Shui.
