The phrase "Three Years, One Song, Two Tears" comes from "After Poetry" written by Jia Dao, a poet in the Tang Dynasty. It means that I spent three years writing these two poems, and I can't help shedding two lines of tears when I read them. The full text is: two sentences in three years, one song and two tears. If I don't appreciate these two poems, I have to go back to my hometown where I used to live and sleep soundly in the rustling autumn wind.
