The virus in Wuhan is spreading rapidly and there is a severe shortage of face masks supply in Hong Kong. On 30th January 2020, Ali Lee (李佳芯) revealed she did not have any face mask and shared the method of using it on Instagram: “You can try to use a cloth with the paper mask. It is reusable and environmental friendly.” However, she edited the post and removed the “reusable” word shortly after and many netizens already saw her original post. Many netizens commented it was a poor method, needed to be disinfected and could not be reused.
