Under normal circumstances, door openings and demolitions must not be carried out without authorization. Otherwise, the entire structural system will be unbalanced and the safety factor of the building will be reduced. Therefore, if you really want to open the door on the load-bearing wall, it must be checked by a professional, and then a professional decoration company will start construction. Ps: The thick solid line in the construction drawing and the wall under the non-supported beam in the ring beam structure are all bearing walls. 
How to see if it is not a load-bearing wall personal decoration can be combined with the following points simply divided into load-bearing walls and non-load-bearing walls: 1, from the housing structure: Generally speaking, brick-concrete structure of all walls are load-bearing walls; frame The walls of a structural house are generally not load-bearing walls. 2, from the housing level: General middle and low-grade residential buildings, villas are brick-concrete structure. High-end are all more than frame structure. 3. Distinguish from the material of the wall tile: The wall of the general standard brick is the load-bearing wall, and the air-filled brick is the non-load-bearing wall. 4, from the wall thickness: 150mm thick wall is a non-load-bearing wall, such as toilets, kitchen more. 5, according to the division of the beam and the wall to distinguish: The oblique brick method must be a non-load-bearing wall. The wall and the beam may be tightly coupled with the load-bearing wall; 6, judging by sound: striking the wall, there is a clear echo, is a light wall, and the bearing wall should not have too much sound. 7, the indoor corner or the wall in the middle of the pillars protruding out of the eight is a frame structure Generally speaking, the walls of the brick-concrete structure of all walls are load-bearing walls; frame structure of the house's internal walls are generally not Bearing wall. 
Whether or not the load-bearing wall can be opened can be explained by professional explanations: If you leave behind the legal constraints and only consider the technical aspects, the load-bearing wall can of course be opened. The key is to strengthen the reinforcement and add the door beam in advance of the door opening. The weight of the original doorway is borne by the walls on both sides of the doorway. Ensure the stability of the structure. The load-bearing wall needs to increase the height and width according to the requirements. According to the difference in the size of the opening, the reinforcement method used is different. Generally, small openings are reinforced with carbon fiber or reinforced with steel. The advantages of these two types of reinforcement methods are quick construction and light weight. They do not need to increase the size of the cross section, but they are only applicable to bearing walls of concrete structures. 
Explanation 2: If the general residence is not a frame structure, the bathroom will be added with a ring beam, that is to say, only the floor of the toilet is made of concrete, and all the open holes will not damage the ring beam. In addition, the channel steel must be embedded during construction, and the width of the door cannot be too large. 
Explanation 3: For the sake of safety, you can find the design unit of the building and ask to calculate the load-bearing coefficient of the load-bearing wall to see if it can be changed. With accurate planning, there will be no major impact during the construction period. The reinforcement plan and demolition construction work shall be completed by qualified professional decoration companies and shall be allowed by the property. Of course, it is generally not recommended that the industry actively use the load-bearing wall, because once the neighbors discover it, they have the right to sue and demand restoration of the load-bearing wall.
