An old residential community plans to install an elevator, which was originally a good thing to facilitate high-floor residents, but it gets involved in the interest entanglement of six households in the whole building. Zhao Guoqiang on the second floor initially agreed to the negotiated compensation and sharing plan, but felt remorse after going home and settling accounts with his family, and came forward to block the construction on the day of construction. After several rounds of tug-of-war, he chose to give up the second-floor elevator stop, got full compensation and saved twenty thousand yuan. But before long, the practical troubles brought by the elderly and children in his family came one after another, and the inconvenience of having no elevator gradually appeared. Zhao Guoqiang wanted to re-add the second-floor stop, but found that the modification would cost far more than the initial cost, and he also had to coordinate the demands of all residents in the building.
