How to write 肓

肓 [huāng] 1. In traditional Chinese medicine, refers to the area above the diaphragm and below the heart. 中医指心下膈上的部位。 2. It is believed to be an area where medicinal properties cannot reach. For example, "膏肓" (gāo huāng) refers to the fatty tissue surrounding the heart, suggesting a condition that is beyond treatment, thus "病入膏肓" implies an illness that has progressed to a point of being difficult to cure. 中医认为这是药力达不到的部位：膏～（中国古代医学称心尖脂肪为“膏”，心脏和膈膜之间为“肓”，认为“膏肓”是药力达不到的地方，所以“病入～～”是指病重到无法医治了）。 【本义】: The basic meaning is the area between the heart and the diaphragm. Traditional Chinese medicine considers it a place where medication cannot reach. 【本义】:心脏与横隔膜之间的部位。中医认为这是药力达不到的部位。 【造字法】: The character is formed phonetically, combining "肉" (meat) and the sound component "亡." 【造字法】:形声。从肉，亡声。 引: 1. "说文": 肓，心下鬲上也。 "Shuōwén": The 肓 is above the heart's diaphragm. 2. "左传·成公十年": 居肓之上膏之下。注:“鬲也。按:心下膏，膏下肓，肓下鬲。” "Zuo Zhuan": Residing above the 肓 and below the fat. Note: "It is also called 鬲. Note that below the heart is fat, below the fat is 肓, and below the 肓 is 鬲." 例: As in: 病入膏肓 (Ancient medicine refers to the fatty tissue surrounding the heart as "膏". The disease is extremely severe and difficult to treat.) 又如:病入膏肓(古代医学称心尖的脂肪为膏。病极严重，难以医治)
