If time travel is possible. I want to take the special flight to Paris.Since the coronavirus broke out around the world,I haven't gone out.Therefore I really miss those places that I have been to.One day I watched a special video accidentally,which told the experience of two boys going from Shanghai to Paris by plane in 2017.When I saw people needn't wear masks,heard pleasant broadcasts ringing ,I feel a wonderful vibes around myself as if I were in Pudong Airport even can recall what I wore When I first came here. And why is the flight special，on account for it can cross the morning dusk line so I think it must be very interesting.Thanks for revising.
