Vanke House Maintenance Center belongs to Vanke Real Estate, which is equivalent to the after-sales warranty service department of Vanke's house (you can understand it as the after-sales department of things like mobile phones). It specializes in providing Vanke owners with quality problems within the contract scope that customers apply for repair during the warranty period. In addition to warranty processing, Vanke's housing maintenance center will also take the initiative to maintain the owner's house.
