Under what background was Liu Wuyun's "I only see your eyes" completed?

In 2003, we faced a sudden disaster, that is, SARS. Everyone avoided it, but great medical staff still rushed to the front line of fighting SARS. Liu Wuyun, a poet, has experienced the test of blood and fire for dozens of days and nights. When he saw the medical staff struggling with death with hard sweat and fearless spirit in the front line of fighting SARS, he was deeply moved, so he wrote this hymn in beautiful words.
