The floor upstairs is always disturbing. What should I do? (Friends who know building decoration please help)

It can be improved, but it is difficult to eradicate. I estimate that your floor is a cast-in-place solid reinforced concrete slab for earthquake resistance. This kind of board has a good performance of blocking sound transmission in the air, but the performance of solid easily transmitting sound directly is not good for you. Stop mode of solid sound transmission: 1, hollow floor. You can't do anything. 2. The upstairs floor is a wooden floor with a keel to block the transmission of solid sound. The initiative lies with the neighbors, you can't do it. 3. Make a sound-absorbing glass fiber cotton ceiling under your ceiling. Can be done, can be improved. Stamping is the direct transmission of sound by solid, and speaking through air is the transmission of sound by gas, which is somewhat different. Loud enough to be heard upstairs and downstairs. If you have insulating glass, close the window and you won't hear it. Your neighbor is not civilized. You are bored to death with him, and you are a little allergic.
