Precautions for epidemic prevention
You can walk upstairs and try not to take the elevator. If you want to take the elevator, you need to wear a mask all the time and try not to touch the elevator button directly. You can put a paper towel on it, such as touching the button directly and washing your hands as soon as you get off the elevator. In the workplace, open the window for ventilation, wear a mask, keep the environment clean, wash your hands frequently and keep your distance. When taking public transport, wear a mask all the time, scan the code to buy tickets as much as possible, and don't take off your mask when sneezing or coughing.
