Our fully self-developed rental app has redefined the rules and regulations suitable for platform transactions. We've developed a complete algorithm that ensures users within the system have access to information earlier and more broadly than users outside the system. From a broader perspective, this reduces costs for tenants (room cost + transportation cost), not just room cost; and increases landlords' revenue (price per unit x number of days used), not just price per unit. Through innovative measures such as multiple listings per room, multiple listings per person, and waitlist orders, the number of listings displayed within the system is more than 10 times greater than traditional methods. Furthermore, the connection between multiple listings and multiple tenants forms a complex and efficient order system, significantly improving rental efficiency. This represents a game-changer for the traditional offline transaction model dominated by salespeople and real estate agents.
