To achieve a simple goal of separating work and personal WeChat accounts, it is crucial to ensure that your WeChat ID, phone, and chat content are clean. A clean WeChat ID refers to a legitimate and unique ID that has not been used by anyone else. A clean phone implies a device that is free from viruses and other malicious software. Clean chat content, on the other hand, means that all messages and conversations are appropriate and do not contain any offensive or illegal content. This is particularly important during the summer season when people tend to spend more time outdoors and may not have access to their computers. By following these simple criteria, you can maintain a clean and organized WeChat account that is easy to manage and use.
