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 shén​shū and 郁垒 yù​lǜ or inscribed with their names.

A poetic name for 春联 chūn​lián, as these paper couplets eventually replaced the original peachwood charms.
