Zhenjiu Jiayi Jing: "The meeting point of hand yangming's collateral". Tongren Shuxue Zhenjiu Tujing and Shengji Zonglu do not have the word "meeting" , do not consider it as a meeting point. Zhenjiu Juying and Zhenjiu Dacheng states: "The meeting point of hand yangming's collateral, hand and foot taiyang meridians, and yang link vessel"; Leijing Tuyi states: " hand yangming's collateral, which connects to Naohui (TE13) of hand shaoyang. Another interpretation: it's the meeting point of hand and foot taiyang and yang link vessel." but foot taiyang bladder meridian (BL) does not reach the upper arm, which seems wrong. As yang link vessel's intersecting point, Binao (LI14) is not mentioned in Shisijing Fahui, Qijing Bamai Kao adds it, which seems to have no basis.
