Pillar or Post?

Tiananmen was the most reproduced non-human image during the Cultural Revolution, and usually just the gateway was depicted. Sometimes one or both Huabiao pillars were included; and sometimes one or more of the ornate lampposts. Although there is no apparent logic to these alternative images, it is noteworthy that a Huabiao pillar could be used as synecdoche to represent Tiananmen as in the example at left.
