The Chinese name, 招手停, (roughly translates to "hail-and-ride") is a small-sized public transportation model in cities where buses would stop upon a passenger's wave and allow boarding or alighting anywhere along the route. This model served as an intermediate option between large public buses and taxis, making it a popular choice in times when public transportation was inefficient and taxis were too expensive.
