Can other owners get a 30% discount on their property fees?

I can't. According to the Measures for the Administration of Property Service Charges, property fees can be discounted, including: the pre-property management residential quarters with government-guided prices are developed by stages and delivered in batches, which causes environmental pollution such as noise and dust to the pre-occupancy owners. You can get a 30% discount on unused properties. There is no service charge for houses not included in the real estate area.
