Who will solve the blockage of the public flue upstairs?

To find a property solution, we must first determine the specific location of the blockage. If you don't know the location, you can hang a rope from the top of the flue, and determine the specific location of the flue blockage according to the length of the rope entering the well. Secondly, it is necessary to determine what caused the blockage of falling in. If it is fragile or soft, you can use the rope transported along the shaft to impact the blockage and let it fall to the bottom of the flue. It can also clear the blockage. If the blockage is non-fragile, it will be a bit troublesome. If the position has been determined, it is necessary to consider cutting the flue to take out the blockage and then restore it. In order to minimize the loss, if the blocking height is located in the blank room, the flue can be directly cut and taken out; If the blockage is located in a decorated room, and the floor below is not decorated, it is suggested to hit the blockage with a rope along the shaft from above, so as to make it descend from the blank room as much as possible.
