One of the eight extraordinary meridians confluence points, Tongyin Qiu meridians. Born from the Yin Qi pulse. Zhenjiu Zishengjing: "Click Suwen‧Qifu Lun "Yinqiao" to note the cloud, it is called Jiaoxin (KI8)... It means that Yinqiao is Jiaoxin (KI8). As for Qixue Lun, the note on "yin-yang Qixue point" says: Yin Qi point is under the medial malleolus, which is called Zhaohai (KI6); Yin Qi is born from Yin Qiu, which is Zhaohai (KI6). , not Jiaoxin (KI8), so nose lower meridian has Jiaoxin (KI8) point on the medial malleolus, and Yinqiao point on the medial malleolus. They are different on the upper and lower sides, but I don’t know. Why are the annotations of Suwen different from each other? Scholars do not believe one annotation but do not examine the other annotation."

[Origin]

Zhao, relative; sea, refers to the soles of feet. When the soles of the two feet meet, there is a depression under the medial malleolus, hence the name. It is also said that the point is opposite to Ran (Burning) Gu, and Burning Gu is Zhaohai (KI6). It is also the crossing point of Yin Qiao channel, so it is also called "Yin Qiao".
