Location of baliao Points
The meridian of the bladder goes up and then descends to go through the 4 sacred holes.
The points are called Shangliao (upper crevasse) V31, Ciliao (second crevasse) V32, Zhongliao (central crevasse) V33 and Xialiao (lower crevasse) V34.
In general, we talk about baliao Points (the 8 liao points, 4 on each side).
