The word "revolution" in English is far more ambiguous and misleading.
"revolve" means "turning around like a wheel. The planet's movement
around the sun is called revolution. E.g., "the earth's REVOLUTION around the
sun has a period of roughly 365 days". When the word "revolution" is used
in this context, it means a periodic repetition and non-essential routine
orbital movement.
However, when referring to political change, it goes exactly the opposite ---
"revolution" means "fundamental and drastic change in power!"

As for "people's republic", there used to be many and there are still quite
a few states or countries titled "people's republic", and only one of whose
official language is Chinese.
