Shandong Dongtai factory sells waterproof closed doors directly at low prices. Welcome to buy.

& Citizen Mr. Zhang: I live in Wharf Yuyuan Community in Chengdu, and there has never been a parking fee. During the National Day, the property management of the community suddenly posted a notice announcing that it would charge a fee, and the monthly charge for each car was as high as a thousand yuan! We, the owners, feel that this sudden price increase is unreasonable. For me, I really can’t afford to park my car! Last year, after the National Development and Reform Commission made it clear that the government would no longer directly intervene in the parking fee standards of residential communities, parking fees in many communities in Chengdu increased one after another, and some even soared from 1 yuan to 3 yuan per month. On September 1, a notice was issued in the Wharf Yuyuan Community in Chengdu, pushing the monthly parking fee to a new high: regardless of the displacement, as long as you park in the community, you will be charged NT$1 per month. The parking fee standards in the community caused dissatisfaction among the owners. After they reported it to the street office, they received a reply that they would coordinate three-party negotiations. On March 1, the property owner said that the price of parking spaces in the community is set by the developer, and the property owner only charges a monthly management fee of 1 yuan per vehicle. As of press time, our reporter was unable to contact the developer.
