The bright lights in the toilet stung your eyes, and you stared at yourself in the mirror and noticed the red blood in your eyes was unusually conspicuous, and you shook your head helplessly. Walking out of the toilet, you decide to take a couple of steps down the aisle of the cabin, as the crowded seats in economy class make you feel very uncomfortable. You rest for a moment and return to your seat. You pass the last few hours of your time on the plane in a daze. You know you are back home when you see the familiar night view of Shanghai through the window. As the plane lands smoothly, you feel very excited but tired. You see a large number of medical personnel in protective suits coming into the front of the cabin dealing with the flight attendants as you wait anxiously in your seat.
