If we only meet for the first time in life, why should the autumn wind grieve over the painted fan? It is easy to change the heart of an old friend, but the heart of an old friend is easy to change. The words of Mount Li are gone. In the middle of the night, tears fall and bells ring. I don't complain. How can it be like the wish of a young man in brocade to be together? This is the first two lines of Li Qingzhao's "Dream Like Order": I often remember that I was drunk at dusk in the stream pavilion and didn't know how to return. At night I return to my boat and mistakenly enter the depths of lotus flowers. Fighting to cross, fighting to cross, startled a pool of gulls and egrets. This was an ancient poem that was often used to express the nostalgia and emotion of one's first love. It expressed the cherishment and nostalgia of people's first encounter, first love, and other beautiful things. At the same time, it also reminds people that with the passage of time, beautiful things may no longer be precious, and feelings may also fade away. Therefore, we must cherish everything in front of us and grasp the present.
