During the outbreak of Severe Acute Respiratory Syndrome (Sars) in China in 2003, she accepted the assignment to work in the temporary Sars ward without hesitation. She worked 12 to 16 hours per day for 83 days without adequate supplies of oxygen and water. She served patients selflessly with love and courage. Her efforts have deeply impressed each of her patients, who come to understand what an “angel in white” really means.
