The original chat record after WeChat's real name is still there. When you change your real-name authentication on WeChat, it usually won't affect your original chat history. The real-name authentication of WeChat account is mainly used to verify the user's identity and has no direct relationship with chat records. Even if the real-name authentication is changed, the WeChat account still retains personal information such as historical chat records. These records are usually tied to your WeChat account, not real-name authentication information. Please note that if you switch devices or log in to WeChat account again, your chat history will also be synchronized to the new device. However, if you actively delete the chat records or use other measures to clear the chat records, these records will not be restored.
