For customers, no matter how good your feng shui is, they won't feel it. It's just your psychological effect.
What customers need is an elegant environment, an atmosphere they like, including decoration, chairs, tables, tableware and so on.
Then your products,,, must constantly innovate under the condition of safety, health and health, and often write new tricks to attract customers,,
Be kind, be friendly to others, respect others' views and opinions, and be considerate of others.
I think your own subjective factors are far more important than the objective factors of Feng Shui.
