1. Liu, a medical officer from Yilin, stated: When needling to treat Phlegm-Qi disorders, first rotate the needle head upward to disperse and move the phlegm, then rotate the needle head downward to vent the Qi.
2. When needling for Pi masses (abdominal lumps), first press with fingers to locate the root of the mass. If it is hard like a finger, use the needle to puncture it frequently until it is broken down, so that the mass may easily dissipate.
3. Yang, a medical officer from Jizhou in the Imperial Medical Bureau, stated: When needling acupoints on the abdomen, have the patient lie supine so that the Zang organs hang towards the back, thereby avoiding injury. He also said: The anterior aspect is deep like a well, while the posterior aspect is thin like a cake. Therefore, when needling the anterior region, depth should be greater; when needling the posterior region, depth should be shallow.
