Tong Wei, also referred to as Penetrating Stomach, is a point on the Spleen channel that is used in conjunction with Tong Shen (88.09) and Tong Bei (88.11).
To locate Tong Wei find the Tong Shen point and measure superiorly 2 cun.
eLotus has an excellent video on how to locate and needle all three of these points.
