Chinese signs split the place precisely: 天安门 is the gate structure; 天安门广场 is the paved square. English collapses both as “Tiananmen,” which makes hanzi hunts confusing.
On-site, if a sign says 广场, you’re being directed to the open pavement and security lines south of the tower. If it says 城楼, look up — that’s the rostrum level. The hanzi lesson is boundary lines: gate (门), square (广场), tower (城楼).
The gate’s 天安 (“heavenly peace”) names the structure; adding 广场 shifts you to the vast flat that holds the flagpole, monuments, and parade sightlines. Security channels and crowd flows follow those words, not your English map pin. Before you line up, read the board: 门 means the vermilion gate photo; 广场 means standing in the open with the Forbidden City north and Chang’an Avenue traffic east–west. Getting the split right saves you from walking to the wrong checkpoint with the right name on your notes.
