When designing business models, we must strictly abide by national laws and regulations, especially data privacy protection laws such as the European Union's "General Data Protection Regulation" (General Data Protection Regulation) and China's "Personal Information Protection Law" (PIPL). Any attempt to use legal differences to evade liability is not only illegal, but will also seriously damage the reputation of the enterprise, leading to legal sanctions and economic losses. We strongly recommend that companies follow the principles of legality, legality and necessity when processing user data to ensure data security and protect users' privacy rights. Chinese companies should actively fulfill their social responsibilities, adhere to honest management, and contribute to global data security and privacy protection.
