Beijing jiahai property

I also want to complain that the noise upstairs disturbs the people, and basically I haven't slept, which makes my family very uncomfortable. Turn on the air conditioner next door in winter, and the air conditioner is very loud. The walls are shaking. I have complained about the property several times, and every time it is perfunctory. The neighborhood Committee also said that I was not at ease at all and called the police, but people said it was useless to call the police. There's really no way to complain now.
