Personally, I feel it's worth visiting. I must not miss this opportunity to visit the thick red walls of the Kremlin when I have time. Here you can imagine many events in Russia and the former Soviet Union, which have a long history. Putin's office building is surrounded by a cordon with police on guard, and no pedestrians are allowed to cross the line. Here you can walk through small gardens, avenues, helicopter aprons, churches and the Kremlin auditorium built during Khrushchev's reign. It is estimated that many Chinese tourists, churches are placed in Chinese leaflets.
