Points: From Pishu (BL20) to Weishu (BL21) and from Zhongwan (Ren 12) to Shangwan (Ren 13)

Technique: Thread the triangular suture needle with the complex  catgut of size 2 to 4, insert the suture needle into the muscle layer from Pishu (BL20), penetrate the suture needle out from Weishu  (BL20) and cut the catgut to embed it in the muscle layer. The same   method is used to embed the catgut between points Zhongwan (Ren 12) and Shangwan (Ren 13). After the operation, the site operated should be covered with the gauge and tape to fix it. Another treatment should  be conducted 15 to 20 days later.
