    In Tung acupuncture a group of three points called Jiu Li, 9 Miles, is located around this point. Zhong Jiu Li, Centre 9 Miles, is located exactly at this point (although described as in the centre of the lateral thigh which would be slightly higher than the TCM description). Shang Jiu Li, Upper 9 Miles, is then located 1.5 cun anterior to this point, and Xia Jiu Li, Lower 9 Miles, is located 1.5 cun posterior to this point. Together they are Tung's go-to points for all disorders of Wind (Chu, 2015).

    Lad and Durve (2008) in Marma Points of Ayurveda locate two points called Uru, one at this point and the other at the greater trochanter of the femur. They are associated with Apana Vayu, Vyana Vayu and Shleshaka Kapha.

    They give the following functions:
    - Balances apana vayu
    - Benefits lower extremities
    - Enhances circulation
    - Relieves pain
