Obviously, he was pregnant with someone, but he just said, "Where did Qiu Si fall?" This shows the poet's deep feelings for Yue Huaiyuan. It seems that Qiu Si is unique to poets.

In the refining of Chinese characters, the word "Luo" is novel, appropriate and extraordinary, giving people a vivid feeling, as if it had fallen into the world with the glory of silver moon.
