This question is not good or bad. 1. How far is the building from the water? If the water exceeds 100 meter, it basically has nothing to do with the building. 2. It depends on whether the water is still water or living water. If it is running water, it depends on the speed of the current. 3. If the water does not flow, it depends on whether the water has peculiar smell or foul gas, and if it does, it depends on the distance from the building. Is this water a big river or a small river ditch or pond? If it is a big river, how wide is it? How high is the water level from the shore? If there are more masters, I won't say anything. All the above points can affect the feng shui of buildings, and it is not a slight influence.
The "water" in geomantic omen refers not only to visible streams and lakes, but also to relatively open plains, ditches, potholes, roads and corridors. When searching for dragons and acupoints or choosing a site to build a house, one inch below the water level can be defined as "water" and one inch above the ground can be defined as a mountain.
Most of the mountainous areas with rivers behind them are dangerous except Pingyang. Whether its feng shui is good or bad needs to be carefully distinguished from Pingyang before making a decision.
