Zhongqing refers to emotional concentration, often referring to love. The words come from the "Preface" by Mengqi of the Tang Dynasty: "Written in a group of books, even though the kitchen is full of kitchens and pavilions, I am particularly fond of him when he touches things and chants."
When Zhongqing and Zifeng met, they fell in love at first sight.
It was such a coincidence that I met you at the first sight. Even though we have been away for three years and more than a thousand days, although you don't remember me, you are still in my heart. This is enough.
