During the new crown pneumonia epidemic, protective equipment such as masks, small bottles of alcohol with 75% concentration, and waterless hand sanitizer should be prepared before you leave on your return trip by car. Prepare ID cards, driver’s licenses, driving permits and other documents and keep them in an easy to reach place. You can also prepare signature pens, as there are quarantine officers at various highway intersections during the epidemic, so you can use your own pen when you need to sign, thus avoiding cross-infection. If the journey is long, it is recommended to bring your own dry food, preferably bread, cakes, cookies, milk and other ready-to-eat foods, so that you can basically ensure that the problem of eating and drinking is solved in the car, thus avoiding contact with the outside world.
