The ceiling of the bedroom is dripping and leaking, my family lives on the fourth floor, the master

In both winter and summer, there is water in the geothermal pipes.

But according to what you say, it doesn't look like a geothermal leak, because it is impossible for the geothermal pipes in the master bedroom and the second bedroom to leak at the same time!

The cast-in-place floor slabs on the building are not actually completely horizontal, they have to be slightly arched, so even if the upstairs floor is leaking, the seepage point should be at the edge of the perimeter, and you are in the middle, which is very strange.

My analysis is that there is a leak somewhere upstairs, not necessarily the fifth floor, it may be higher, this water source is not necessarily the water in the bathroom, kitchen, or it may be outdoor rainwater, and the leaked water happens to enter the lighting line of your home, and finally flows out of the position of the lamp head box in the middle of the room.

Look for water seepage on the surrounding walls.

The ceiling is not very flat, you don't pay attention, you find a wooden stick (don't hold it too flat), slowly drip water from the head, you will find that the water flows down from that end, if the stick is not straight enough to bend down a little, the water will flow down from the middle part of the bend, you try it, right!

There must be something wrong with the water pipes. It's just that you didn't find it!

Suppress the upstairs water, geothermal, if there is no problem, see if it is a bathroom leak or exterior wall, the same kind of analysis, will always find the water source, more information, better advice, free concrete waterproof leakage repair technical advice, to avoid today's repair, tomorrow's leakage, every year repair, every year leakage troubles.
