十七遇她七十与他

'At seventeen I met her, at seventy Im with him.' This nickname tells a story: the narrator had some memorable first encounter with somebody important at age 17, and then later on they were again together when 70 years passed. This is likely to imply a lifelong love story or a long lasting friendship. This sort of title expresses both fondness for youth and appreciation for the passage of time with cherished ones.
