Charms made of two peachwood boards used in ancient times to ward off evil; they were hung by the door and either painted with the images of the gate gods 神荼shénshū and 郁垒yùlǜ or inscribed with their names.
Spring Festival couplets
A poetic name for 春联chūnlián, as these paper couplets eventually replaced the original peachwood charms.
