==Names==
Kaifeng's official one-character abbreviation in Chinese is {{lang|zh|汴}} (''Biàn''). Historically it has also been known as:
*''Junyi'' (浚儀)
*''Dàliáng'' ({{lang-zh|c=大梁}})
*''Biànliáng'' ({{lang-zh|labels=no |c=[[wikt:汴梁|汴梁]]}})
*''Biànzhōu'' ({{lang-zh|labels=no |c=汴州}})
*''Dōngjīng'' ({{lang-zh|labels=no |t=[[Dongjing (disambiguation)|東京]]}})
*''Biànjīng'' ({{lang-zh|labels=no |c=汴京}})
The area was named "Kaifeng" after the [[Qin dynasty|Qin]]'s [[Qin's wars of unification|conquest of China]] in the second century BC. The name literally means "opening the border" and figuratively "hidden" and "vengeance".{{cite book |script-title=zh:中国古今地名大辞典 |year=2005 |location=Shanghai |publisher=[[Shanghai Lexicographical Publishing House]] |page=348 |language=zh-hans}} Its name was originally Qifeng ({{lang-zh|t=啓封}}), but the syllable ''qi'' (Baxter-Sagart: /*kʰˤijʔ/) was changed to the essentially synonymous ''kai'' (/*Nə-[k]ʰˤəj/, /*[k]ʰˤəj/) to avoid the [[naming taboo]] of Liu Qi ([[Emperor Jing of Han]]).
==Administration==
The [[prefecture-level city]] of Kaifeng administers five [[district of China|districts]] and four [[County (People's Republic of China)|counties]]:
*[[Longting District]]

*[[Yuwangtai District]]
*[[Xiangfu District]]
