yes, there is first check to get even inside train station, you must have ticket, then right after that is security check, then in some stations there is another check to enter boarding room, then to leave boarding room to platform there is another check and then in the train they check your ticket again, also when leaving station in destination they will again check your ticket to let you go

it's HSR with communist characteristics

no thanks, i will rather use show train in Europe where i can walk straight from my room to train with ticket in my mobile instead of Chinese harassment with thousands of people pushing you all around, it's just one disgusting experience, even Chinese airports are faster and more pleasant
