What do you mean your uncle will always be your uncle?

"Your uncle will always be your uncle" is a network stalk, which originated from a dialogue in the classic essay "Saying Things" co-authored by Zhao Benshan and Song Dandan in the Spring Festival Evening of 2006. The complete form is "Your aunt is no longer your aunt six years ago, and your uncle will always be your uncle". This kind of stalk has become popular on the Internet, mainly in some communities, such as Post Bar, where users reply prepositions in posts or replies to show their contempt for each other.
