2 157 is actually a homonym: I love you all my life. Usually, this word appears in modern young couples. Because I hate typing trouble, many conversations are directly replaced by pictures or numbers, which makes me look avant-garde, so that people born after 80 don't know what these chats mean when they see them.

The meaning of this stalk: the original intention is to show that I love you very much, and I don't need those disgusting words to express it.

Source: unable to verify. It must be an online language sent by young people now, and everyone is gradually using it.

Usage scenario:

On Valentine's Day, Lin Xiaomei received a big cake. There is no fancy decoration on it. Only the numbers "2 157" are very eye-catching, but my sister thinks it is very sweet.

On Christmas Eve, Lin Xiaomei received a message from her boyfriend who was far away from home. Although there are only four numbers like "2 157", she deeply feels her boyfriend's love.
