Wikipedia:
The Chinese name of the gate, Tiānānmén 天安門 …
is made up of the Chinese characters for "heaven,"
"peace" and "gate" respectively, which is why the
name is conventionally translated as "The Gate of
Heavenly Peace". However, this translation is
somewhat misleading, since the Chinese name is
derived from the much longer phrase "receiving the
mandate from heaven, and stabilizing the dynasty."
