Yu Pingxian, the owner of the first floor, had a conflict with his upstairs neighbor over the installation of an elevator. He was considerate of the old man's concession and only agreed to install a corridor elevator. Unexpectedly, Aunt Li and others took advantage of his business trip to build an ordinary elevator, ignoring the loss of lighting and noise, and forced him to share the elevator fee. Enraged, Yu Pingxian turned his home into a columbarium to fight back, and forcefully defused the neighbors to call the police, report, mediate and put pressure on them. In the end, the owners upstairs started fighting among themselves and forced Aunt Li to pay a large sum to buy her house. Yu Pingxian escaped smoothly, and the evil-doing neighbors fell into endless neighborhood disputes.
