How about planting an elm tree and a neem tree after returning home?

In geomantic omen, a tree is a tree, and the varieties of trees are not subdivided. If someone says that, it's just grandstanding.

The information you gave is too simple to make any effective feng shui analysis.

Maybe you don't know much about Feng Shui. Let's give you an example of the general process of seeing Feng Shui in Yangzhai, so that you can understand it.

Feng Shui is a profound knowledge, and it is a treasure in China's culture for thousands of years. It is to comprehensively observe the surrounding environment of this house (including this floor and this building), accurately measure the sitting direction of the house and the building, observe the cubicle and the small environment in the house, and analyze a lot of information such as the life of everyone living in it. Then, according to the principle of geomantic omen, we should first avoid or dissolve all suffocation and arrange everyone's bed and desk.

If you really believe that Feng Shui will affect your luck, you should formally ask a Feng Shui master to do a field survey of your house.

Or, you should at least provide the floor plan of the mountain or street around the building, the overall floor plan of your house, the internal zoning map of your house, and the exact direction (degree) of the building, so as to analyze it for you from the perspective of geomantic omen.
