Hanoi at night is peaceful with couples chatting on stone benches by West Lake, with girls playing the piano, readers in the library... Not only that, Hanoi at night is also the quiet, urgent life of working people. Students diligently study, teachers diligently prepare lesson plans, welding lights flicker in the night. Doctors treat patients, workers on duty, police officers on patrol, Nhan Dan Newspaper Printing Factory works tirelessly at night.
