One inch of loyalty is to serve the country, two lines of clear tears are to miss relatives - the words come from the poem "Reminiscing on the Beginning of Spring" by Yu Qian of the Ming Dynasty. Later, someone changed it to "An inch of loyalty is to serve the country, and two lines of pure tears are to miss lovesickness."
I long to serve the country with my whole heart; I am in a foreign country, and I can't help but shed tears when I miss my relatives. The two lines of the poem describe the author's emotional ups and downs. Danxin: A sincere heart.
