I took a Turkish flight and transferred to Amsterdam in Istanbul. Do I need to transfer my checked baggage during the transit?

There must be no Chinese information desk. I suggest you confirm whether Turkish Airlines will check your luggage through Amsterdam when you check in at home. Generally speaking, there is no problem. So all you have to do in Istanbul is take your carry-on luggage and find the boarding gate.

There are only two passenger terminals in Istanbul, one is a domestic flight and the other is an international flight. Don't worry about connecting to the terminal, it will only be in one terminal. Moreover, both flights are Turkish Airlines. If it is standard service when getting off the plane in Istanbul, there will be a ground sign to pick up connecting passengers. If not, it is not difficult. Before you leave home, you will get boarding passes for two flights. All you have to do is follow the boarding gate indicated by the boarding pass to Amsterdam and find the corresponding boarding gate according to the airport sign after getting off the plane.
