Just as the Americans have Halloween, the Chinese have the Hungry Ghost Festival (also known as Zhong Yuan Jie in Chinese), when the souls of the dead are believed to roam the earth.
According to custom, these ghosts can get up to mischief if ignored so all sorts of offerings are made during this period, which is the seventh month in the lunar calendar.
Large tents are set up in open fields to host raucous dinners and auctions in heartland estates like Ang Mo Kio and Yishun. There are performances too, such as Chinese operas and 'getai' (literally ‘song stage’ in Chinese, or live stage performances), which feature tales of gods and goddesses, bawdy stand-up comedy, as well as song and dance numbers.
