Core Viewpoint - Zhuanzhuan, a well-known second-hand trading platform in China, is shifting its business model from C2C to C2B2C, closing its "free market" operations that have been running for ten years, in response to competitive pressures and trust issues in the C2C model [1][2][11]. Summary by Sections Business Model Transition - Zhuanzhuan will gradually shut down its core C2C "free market" business, starting with the closure of personal product posting on September 24, followed by the removal of browsing and purchasing options by September 29, and the final closure of customer service by October 31 [4][5]. - The platform will now focus on C2B2C, where sellers can sell items through recycling, consignment, and listing, with the platform providing official quality inspection services [5][6]. User Impact - The closure of the free market will significantly impact specific user groups, particularly those trading niche items like collectible cards and dolls, who may find it difficult to adapt to the new model [9][11]. - Users have expressed concerns over the higher prices of officially inspected items and the platform's shift towards self-operated sales, making it harder for ordinary sellers to complete transactions [7][11]. Trust and Quality Issues - The C2C model has faced trust challenges, including online fraud and gray market transactions, which the platform struggled to manage effectively [11][12]. - Quality issues in second-hand goods, such as undisclosed defects and counterfeit products, have led to a poor shopping experience for consumers [12][14]. Operational Challenges - The new C2B2C model requires Zhuanzhuan to invest more resources in quality inspection and after-sales service, as the platform will now be directly responsible for these aspects [15][16]. - While the official inspection model aims to enhance trust in transactions, it may also increase operational costs, which could be passed on to consumers, necessitating a balance between cost control and user experience [16].
