The Ren Mai (Conception Vessel) has twenty-four acupoints along the midline of the body. Huiyin (CV1) is hidden between the two yins (anterior and posterior orifices). Before Qugu (CV2) lies Zhongji (CV3); Guan Yuan (CV4), Shimen (CV5), and Qihai (CV6) are arranged in sequence. Yinjiao (CV7), Shenque (CV8), and Shuifen (CV9) are located here; Xiawan (CV10), Jianli (CV11), and Zhongwan (CV12) are anteriorly positioned; Shangwan (CV13) and Juque (CV14) connect to Jiutui (CV15); Zhongting (CV16), Danzhong (CV17), and Yutang (CV18) are linked; Zigong (CV19) and Huagai (CV20) follow Xuanji (CV21); Tiantu (CV22), Lianquan (CV23), and Chengjiang (CV24) are at the terminal end.

Huiyin (CV1) of the Ren Mai (Conception Vessel) is located between the two yins; Qugu (CV2) is secured in the depression at the pubic hairline; Zhongji (CV3) is located four cun below the umbilicus; Guan Yuan (CV4) connects three cun below the umbilicus; named Shimen (CV5) is two cun below the umbilicus; Qihai (CV6) is fully situated one and a half cun below the umbilicus. Yinjiao (CV7) is one cun below the umbilicus; Shenque (CV8) is exactly at the center of the umbilicus; Shuifen (CV9) is one cun above the umbilicus; Xiawan (CV10) is listed two cun above the umbilicus; Jianli (CV11) is named three cun above the umbilicus; Zhongwan (CV12) is approximately four cun above the umbilicus; Shangwan (CV13) is five cun above the umbilicus; Juque (CV14) is six cun and five fen above the umbilicus; Jiutui (CV15) is five fen below the xiphoid process (mastoid bone); Zhongting (CV16) is taken six cun below Danzhong (CV17); Danzhong (CV17) is indeed between the two breasts; Yutang (CV18) governs one cun and six fen above Danzhong (CV17); Zigong (CV19) is three cun and two fen above Danzhong (CV17); Huagai (CV20) is raised four cun and eight fen above Danzhong (CV17); Xuanji (CV21) is five cun and eight fen above Danzhong (CV17); Tiantu (CV22) protrudes one cun above Xuanji (CV21); Tiantu (CV22) is approximately four cun below the larynx; Lianquan (CV23) is determined at the tip of the hyoid bone under the chin; Chengjiang (CV24) is under the lip ridge at the front of the cheek; the Ren Mai (Conception Vessel) travels within the abdominal midline.

[Note] Huiyin (CV1) is located in the middle of the anterior and posterior orifices; it is the starting point of the Ren Mai (Conception Vessel), Du Mai (Governing Vessel), and Chong Mai (Penetrating Vessel).
