The rented house short-circuited the wires. What should I do?

I have dealt with this problem before. If it is an old-fashioned building, the branch of the light line is usually in a buried box in the wall nearest to the ceiling lamp, 30 cm away from the ceiling. And at that time, it was usually 1.5 copper wire or even aluminum wire. . What I can tell you is that as long as it is a building, it can be rerouted and repaired. . If the thread is not burned much, the owner can pull it out with a vise, usually a little. If it is too short, you can find its tap (where the thread comes from) to find out which thread it is, and just extend it (or replace the whole thread). . Of all the steps, one is the most important: you must pull down the main switch first. . . In addition, if the owner is a lady or has poor hands-on ability, I have a little suggestion: go and see if there is any decoration there. Find a decorator. . . Must be decorated. . . It should be done well. . But it will cost a small sum of money and then ask the landlord for reimbursement. . I am really rich and frugal. . Hey, hey, solve the problem from reality. . . But the electrician at work is useless. . . .
