To change Pinduoduo to Taobao, we must first understand the differences between the two and user needs. Secondly, we need to reposition and redesign the platform's functions and interface to make it more in line with Taobao's usage habits and brand image. At the same time, we need to launch shopping and transaction functions similar to Taobao to attract Taobao users to transition to the new platform. In addition, we need to increase marketing and promotion efforts to increase the platform's popularity and number of users. Finally, we need to continuously improve and optimize the user experience to ensure that users can use the new platform smoothly after switching.
