What does it mean to wake up for three years in long summer?

It means that someone or a situation wakes up from a dream, and after three years, it finally reaches the solar term of long summer. Long summer, who has been awake for three years, can indicate that a person has gone through a long period of time after waking up from a dream, and finally it is the beginning of summer. This poem means that a person or a situation has experienced a long wait, suffering or change, and finally ushered in a new stage or a new beginning.
