Welcome to FT, BrusViet3!

Although you don't say so directly, I assume that you are inquiring about arriving by train at CDG at 11:53 and departing from there at 13:10 on a flight to Vietnam. While I have never taken a train to CDG, I am familiar with the airport, as I have taken flights originating there and also connected there before and after transatlantic flights. I could be wrong, of course, but I cannot imagine that you are allowing yourself sufficient time with your current plans. If you miss your connection, when is the next possibility for you to fly from Paris to Hanoi?
