Grouping lunar new year decoration tags

Looking to clear up related tags but not sure which ones to keep and its getting hard to track, hoping users with more chinese cultural knowledge can chime in.
One of the common decorations with words are called "chunlian" ("fai chun" according to wiki), which supposed to be the umbrella term, these includes the square paper posted on doors ("doufang_chunlian") or its variant that is turned 180 deg ("dao_fu"); and also pairs of writing on sides of doorway or as scrolls, these pairs are "duilian"

Should these tags: dao_fu, doufang_chunlian, chunlian_writing, chuntiao, antithetical_couplet to be group under chunlian/fai_chun?

umbrella term: chunlian (pinyin) / fai chun (dialect)
square variants: dao_fu / doufang
rectangle variants: chuntiao / duilian / antithetical_couplet

Do add info if I missed anything

Both chunlian and doufang for Fu are Chinese new year decorations, but doufang is not a type of chunlian. In Chinese, word “duìlián” and “chūnlián” (Spring Festival duilian) specifically refer to the couplets usually pasted on both sides of the door.
