The ji was a Chinese polearm used in one form or another for over 3000 years, from at least as early as the Shang dynasty until the end of the Qing dynasty. They are still used for training purposes in many Chinese martial arts.
In the Song dynasty, several weapons were referred to as ji, but they were developed from spears, not from ancient ji. One variety was called the qinglong ji , and had a spear tip with a crescent blade on one side. Another type was the fangtian ji , which had a spear tip with crescent blades on both sides. They had multiple means of attack: the side blade or blades, the spear tip, plus often a rear counterweight that could be used to strike the opponent. The way the side blades were fixed to the shaft differs, but usually there were empty spaces between the pole and the side blade. The wielder could strike with the shaft, with the option of then pulling the weapon back to hook with a side blade; or, he could slap his opponent with the flat side of the blade to knock him off his horse.
Jī was the ancestral name of the Zhou dynasty which ruled China between the 11th and 3rd centuries BC. Thirty-nine members of the family ruled China during this period while many others ruled as local lords, lords who eventually gained great autonomy during the Spring and Autumn and Warring States periods. Ji is a relatively uncommon surname in modern China, largely because its bearers often adopted the names of their states as new surnames.
The character is composed of the radicals ( Old Chinese: nra, "woman") and (OC: ɢ(r)ə, "chin"). It is most likely a phono-semantic compound, with nra common in the earliest Zhou-era family names and ɢ(r)ə marking a rhyme of (OC: K(r)ə).
The legendary and historical record shows the Zhou Ji clan closely entwined with the Jiang , who seem to have provided many of the Ji lords' high-ranking spouses. A popular theory in recent Chinese scholarship has suggested that they represented two important clans the Ji originally centered on the Fen River in Shanxi and the Jiang around the Wen River in Shaanxi whose union produced the Zhou state ruled by Old Duke Danfu, although the theory remains problematic.
Ji ( Tamil: ஜி) is a 2005 Tamil action film directed by Linguswamy and produced by S. S. Chakravarthy. The film stars Ajith Kumar and Trisha Krishnan in the lead roles, while the score and soundtrack are composed by Vidyasagar. The film was released in February 2005 following a series of delays and received mixed reviews which leads to disaster to the producer.
There are two different kana letters that are romanized as ji.

- The kana ぢ is primarily used for indicating a voiced consonant in the middle of a compound word and can never begin a word.

Ji was an ancient state in northern China during the Shang and Western Zhou dynasties from at least the 11th century to the 7th century BC. The state was based in the walled City of Ji, or Jicheng, located in the modern day Guang'anmen neighborhood of southwestern Beijing. Around 7th century BC, Ji was conquered by the larger State of Yan, which took the City of Ji as its capital. The city remained the primary urban center in the area until the 13th century, when Kublai Khan built the larger city of Dadu to the northwest, which eventually absorbed the City of Ji.
Ji is the pinyin romanization of a number of distinct Chinese surnames that are written with different characters in Chinese. Depending on the character, it may be spelled Jī, Jí, Jǐ, or Jì when tone diacritics are used. In Wade–Giles they are romanized as Chi. Languages using the Latin alphabet do not distinguish among the different Chinese surnames, rendering them all as Ji or Chi.
Jī is the Mandarin pinyin romanization of the Chinese surname written in Chinese characters. It is romanized as Chi in Wade–Giles and Kai or Gai in Cantonese. Ji is listed 194th in the Song dynasty classic Hundred Family Surnames. Relatively uncommon, it is not among the top 300 surnames in China.
Ji, also spelled Jee, Chi, or Chee, is a Korean family name, as well as a popular element in Korean given names. The meaning differs based on the hanja used to write it.
