Jinchang joke

Hello, as stipulated in the commercial housing sales contract signed between you and the developer, there is a clause of "cement mortar screeding of interior walls" in the delivery conditions, and the developer is obliged to provide interior walls and screeding them with mortar. According to what you said, you should take a class action lawsuit with other property buyers, sue the developer and demand compensation for the losses caused to the owner because the delivered interior wall does not meet the agreed conditions. You can entrust the builder to budget the cost of interior wall masonry and mortar plastering first, and then sue accordingly, or you can settle the cost with the builder after actually laying the wall and mortar plastering, and then sue the developer after getting the bill.
