Revised Romanization of Korean
"Jin" is the Revised Romanization of Korean , originally written in Korean Chinese characters (hanja). This character's Old Chinese pronunciation has been reconstructed as and originally referred to the 5th earthly branch of the Chinese and Korean zodiacs, a division of the orbit of Jupiter identified with the dragon. This was associated with a bearing of 120° (between ESE and SE) but also with the two-hour period between 7 and 9 am, leading it to be associated with dawn and the direction east.
