Couplets on a traditional wooden door in a village in Laoshan.
From Wikipedia:
“In Chinese poetry, a couplet (simplified Chinese: 对联; traditional Chinese: 對聯; pinyin: duìlián) is a pair of lines of poetry.
Outside of poems, they are usually seen on the sides of doors leading to people’s homes or as hanging scrolls in an interior.
Although often called antithetical couplet, they can better be described as a written form of counterpoint. “
