Bus = 公车 [gōng chē]
A bus launches off a hilltop like a stunt car to a shout of “Yahoo!!”, while two people below gasp “Cool!” and “God!” That flying vehicle is a 公车.
公车 (gōngchē) means “bus,” short for 公共汽车 (gōnggòng qìchē), “public car.” It is the usual word in Taiwan; in mainland China people mostly say 公交车 (gōngjiāochē), and 公车 there can also mean a government car.
To take the bus is 坐公车 (zuò gōngchē). A bus stop is 公车站 (gōngchēzhàn).
我每天坐公车上班。 — Wǒ měitiān zuò gōngchē shàngbān. — I take the bus to work every day.
公车来了！ — Gōngchē lái le! — The bus is here!
