The main sources of infection for novel coronavirus pneumonia are people and asymptomatic infected persons. If you go to a place where no one is around, there is no need to worry about (novel) coronavirus pneumonia. If there are no other people within 2m of you outdoors, you can also avoid wearing a mask. You can get fresh air, you can do exercise, and you can maintain a better mental and physical state to help fight the outbreak. You should avoid going to places that are too remote and you need to keep your communication open in case you are unwell and cannot contact others, which is not conducive to seeking medical attention. Therefore, it is important to encourage outdoor exercise during the epidemic and to ensure that communication tools are open and that you can contact someone for help at any time.
