Beijing street vendors have traditionally used a variety of calls and songs (吆喝) to cry out their wares.

Once the most common form of advertising in the capital, these traditional calls are becoming extinct. People who live in apartment buildings buy their goods from supermarkets, and the last generation of street hawkers who know the old cries will not be around for much longer.

Muzimei shot the video below of an old man demonstrating various cries. His name is Yang Changhe (杨长和). The Beijing News published a story about him a few days ago: The famous mouth of the park VS the football referee (in Chinese).
