The new virus variant Omicron is currently wide spreading in Hong Kong and the weather turns cold as well. As a mother of 3 daughters, Gigi Lai (黎姿) shared a method to keep herself warm and posted an online message: “It is one of the methods which keeps me warm. I place foot warmer into microwave and use it before sleeping at night. It helps to improve blood circulation and sleep quality. Please keep yourselves warm and take good care.”
