The decline rate narrowed significantly comparedwith the same period of 2024, indicating that the market is gradually bottoming out. Amid this environment, FangDD has been strengtheningdevelopment of core projects and in-depth cooperation with reputable developers and and business partners. As a result, the GMV and revenuehave both increased simultaneously. Meanwhile, the company is also continuously exploring and innovating in new business areas.
