1. For example, Sanqiu refers to three seasons, which is nine months, and usually refers to a long time. Not seeing each other for a day is like three autumns. It is a common sentence in ancient books and history books. It means not seeing each other for a day is like a long time. It is like missing you very much. It is often used to describe the mood of living like a year. The three autumns here do not refer to the specific time. It means It's been a long time.
2. The word "Rugui Sanqiu" first came from the "Book of Songs", and can often be seen in some poems in the Book of Songs, such as "Zheng Feng Zijin" and "Wang Feng Picking Ge". It is used to express that one misses someone very urgently and wants to see each other again immediately.
3. "Wang Feng: Picking Ge" is actually an ancient love poem. It describes the feelings of an infatuated young man and the girl he loves who miss him so much after being separated for just one day. Although "Three Autumns" is too exaggerated, it deeply reflects the feelings of a man and woman in love who live like years after separation.
4. Nowadays, many people still use the phrase "a day without seeing each other is like three autumns apart", but it is not only used to express love, but can also be used to express the incomparable sadness after separation from friends and relatives. The feeling of longing shows that the relationship between two people is strong and inseparable.
