Coronavirus is declared a pandemic and makes the citizens from the entire world very worried. Recently, Louis Koo (古天樂) is transformed into a DJ and rooted for everybody while filming an advertisement: “Good morning, Hong Kong citizens! I believe we have “dark clouds” over our heads upon waking up every morning and the number of confirmed cases make you wonder if you are one of them. Yes, we must stay vigilant and depend on a certain medicine, “stay strong” for our determination. We are different when compared to 17 years ago and must continue to smile in our hearts.”
