On the frontolateral side of the lower leg, 9 cun below the Calf's Nose (ST-35), one horizontal finger (the width of the middle finger) from the anterior edge of the tibia. (This acupoint is bilateral, one on each side.)

Sit with your knees bent. First, locate the position of the "Ribbon Opening (ST-38)" acupoint (refer to "Ribbon Opening"). Measure one horizontal finger width downward from Tiaokou, and you can feel a depression between the tibia and fibula, which is the location of this acupoint.
