The floor drain is filled with water, the foot of the toilet bowl on the side of the floor drain including the screw holes should be sealed, check whether the sewer pipe of the washbasin and the connection of the underground sewage pipe are sealed, my house is inserted without sealing, so there is a smell running out of the interface. Seal it with electrical tape or glass glue. It's all done and the bag is odorless
