From March, they worked at a community treatment facility at the AsiaWorld-Expo complex on the island of Chek Lap Kok, caring for COVID-19 patients, mostly seniors.

During one morning shift, Luo nursed an elderly patient and reminded her to take her medicines.

The woman noticed the name tag on Luo's protective suit, and after a brief conversation she learned that Luo comes from her own hometown, Guangzhou, capital of Guangdong province.

While holding Luo's hand, the patient recalled her childhood memories of Guangzhou. She invited Luo to have dim sum with her in the city when the epidemic is over and cross-border travel resumes.

She also took a photo of the two of them, and with Luo's help sent it to her two daughters. The woman told her children not to worry about her because the nurses were looking after her well.

Luo's eyes filled with tears. She said that if her mother had been infected and taken to the hospital, she would also have been worried.
