What should I do if the back door of my yard is blocked? Ask for help

If you are a patient and kind person, obey the wishes of the elderly, after all, they are also. . . . The old man is stubborn, taking the front door instead of the back door. If the back door is useful, the landlord is violent, and the other party is in charge of young people, discuss it and enforce it according to your meaning. If they block it again, it will be illegal, and the home will be yours. You can sue them.
