Yes: the first realm is "establishing", the second realm is "keeping", and the third realm is "getting". The first realm is determination and determination. Only when this condition is met can the second and third realms be achieved. The phrase "three realms of life" comes from Wang Guowei's "Human Words".
Mr. Wang Guowei quoted these famous sentences from the works of several great poets in ancient times to talk about the three realms of learning. The original meaning of the words is obviously mostly about the private relationships between children and children. However, Mr. Wang Guowei cleverly used it to talk about the realm of learning. To the point, explained very thoroughly.
