I run a small shop in the IT industry, opposite which sells tricycles. Are there any feng shui taboos?

Whether it's home feng shui or business feng shui,

Its conditioning does not need to be deliberately conditioned with some dissolved substances.

The highest realm of feng shui conditioning is not to use evil things.

But to adjust the layout of furniture, or to manage the location of goods,

In order to achieve a balance between yin and yang,

So from your description, it's not just your store that has problems.

There should be something wrong with your internal layout.

The most intuitive thing is to enter your store.

The first impression is clutter,

So don't deliberately look for problems only from feng shui.

Feng shui is just a catalyst,

Not everything,

While conditioning Feng Shui,

Pay attention to finding symptoms from yourself,

In order to maximize the benefits.
