My building is on the fourth floor, the north building, and there is a telephone pole 6-7 meters outside the south wall. Does it taste good? From the perspective of feng shui.

No problem:

The north building faces south and there are telephone poles in the south. In fact, it is taboo, and it is called the top evil spirit in geomantic omen, which is not good for laymen. But you are on the fourth floor, the height should be more than 9 meters, and the height of telephone poles is generally below 10 meters, and some of them are buried underground, so the telephone poles should be below your floor, which has no influence. Don't worry.

If you are really uneasy, hang a gossip mirror on the pole for good luck.
