What was the meaning of an online language ID? Why does it mean goodbye?
An ID was an online language that referred to another name or ID that a person used on the Internet. In different online communities, the meaning and usage of a fake identity may be different, but it usually refers to another name or ID that a person repeatedly appears in different posts or uses to hide his true identity. On some novel websites, readers might encounter multiple authors publishing different versions of the same novel. Sometimes, these versions would have different authors and IDs. This was the function of the avatar. An author could use a fake ID to protect their privacy and use different IDs in different works to improve the legibility of the work. As for the meaning of the ID 3166, I'm not sure if it's specifically used to mean goodbye. 3166 may have many meanings and usages in different online communities and cultures. It may need to be understood according to the specific context.
