Temu is a cross-border e-commerce platform under Pinduoduo, which adopts a "semi-hosted" model. In this model, sellers are responsible for products, shipping and customer service, while the Temu platform is responsible for providing traffic, payment and logistics services. Unlike the full-hosted model, the semi-hosted model gives sellers greater control, allowing them to manage their stores independently and adjust product strategies according to market demand, thereby achieving more flexible operations and faster growth.
