We have established a comprehensive after - sales service network and a rapid response mechanism. When customers encounter product problems during use, they can get a response from us immediately. We offer a 7×24 - hour after - sales service hotline, and professional after - sales technicians will promptly answer customers' questions and provide solutions. For products that require repair, we will arrange special personnel to pick up the items or provide nearby repair service points to shorten the repair cycle and reduce customers' waiting time.
