Commemoration
The conduct of commemoration activities at the Monument to the People's Heroes is regulated by the Major Events Administration Office of the Tiananmen Area Administrative Committee. Strict rules apply to conduct within the vicinity of the monument. In particular, climbing the monument beyond the protective barrier without prior approval is prohibited, as is photography and filming. Those intending to lay wreaths at the monument must apply five days in advance.
Since 1980, it has been customary for visiting foreign dignitaries, especially from historical allies of the People's Republic of China, such as post-Soviet states, to lay wreaths at the monument when visiting Beijing. Certain domestic groups, such as police and military units, would also sometimes lay wreaths at the monument.
