Whenever Hong Kong Foot (a disease characterized by swelling, pain, and weakness in the feet) initially presents with foot weakness, moxibustion should be performed promptly. Concurrently administer Zhuli Tang (Bamboo Juice Decoction). After moxibustion, Bafeng San (Eight Winds Powder) may be taken; there are no cases that do not recover, provided treatment is swift. If a patient undergoes only moxibustion without taking the powder, or takes the powder without moxibustion, the condition will be half-recovered and half-critical. Even if recovery occurs, it may relapse after one to two years. Those who feel discomfort and immediately follow this method—performing prompt moxibustion and taking the powder—will see ten out of ten cured.

The sequence for initial moxibustion is: first Fengshi (GB31), then Fubu (ST32), then Dubi (ST35), then Xiyan (EX-LE5), then Zusanli (ST36), then Shanglian (EX-LE9), then Xiaolian (EX-LE10), and finally Jieggu (GB39).

Regarding these eight acupoints:
First, Fengshi (GB31): Have the patient stand upright with arms hanging straight down, fingers spread, covering the thighs. The tip of the middle finger indicates the point on the large thigh muscle. Moxibustion of 100 moxa cones (Zhuang) is recommended; more is acceptable. For mild cases, do not reduce below 100 Zhuang; for severe cases, up to 500–600 Zhuang at one site. Do not apply all cones at once; divide into three sessions for better results.
Second, Fubu (ST32): Have the patient sit upright. Place the patient's hand across the bent knee. The lower edge of the hand aligns with the knee cap, and the upper edge side corresponds to the center. Moxibustion of 100 Zhuang, or alternatively 50 Zhuang.
Third, Dubi (ST35): Located at the lateral border of the patella, on the flat area outside the bone edge. Pressing with the hand reveals a joint gap. Alternatively, located below the knee, between the three lateral bones near the heel; pressing while moving the ankle reveals a hollow sensation. Moxibustion of 50 Zhuang, up to 100 Zhuang.
Fourth, Xiyan (EX-LE5): Located in the depressions on both sides below the knee cap.
Fifth, Zusanli (ST36): Located one Fu (a traditional measurement unit based on the patient's hand span) below the knee joint, adjacent to the outer tibia. Alternatively, three cun below the knee joint. Measurement should be based on the patient's hand size. Moxibustion of 100 Zhuang.
Sixth, Shanglian (EX-LE9): Located one Fu below Zusanli (ST36), also adjacent to the outer tibia. Moxibustion of 100 Zhuang.
Seventh, Xiaolian (EX-LE10): Located one Fu below Shanglian (EX-LE9), also adjacent to the outer tibia. Moxibustion of 100 Zhuang.
Eighth, Jieggu (GB39): Located one Fu above the lateral malleolus, or alternatively four cun.

For these points, moxibustion need not be completed in one session. It is advisable to perform daily sessions over three days to complete the prescribed number of Zhuang. Treat one foot if the disease is unilateral; treat both feet if bilateral. Foot weakness often affects both feet. Another prescription suggests: upon feeling foot discomfort, moxibustate Zusanli (ST36) and Jieggu (GB39) at one site each; if both feet are affected, treat four sites total. The quantity depends on severity, but generally, even mild cases require no less than 100 Zhuang. If ineffective, proceed sequentially; more is better. Another view holds that moxibustation of Jieggu (GB39) is most critical. If foot weakness is untreated and pathogens enter the abdomen causing abdominal distension and Qi rebellion, a major moxibustion protocol is required, treating various meridians, joints, and abdominal/back areas, combined with Bafeng San (Eight Winds Powder), often resulting in recovery. If the patient cannot tolerate full-body major moxibustation due to pain, moxibustating chest, heart, abdominal, and foot acupoints can still yield good results.

The measurement of "one Fu" is defined as the width of four extended fingers placed together, measured across the proximal interphalangeal joints. There are two types of Fu measurements; while some use three fingers, foot weakness moxibustation uses four fingers. This follows the old methods preserved by Zhi Facun. Other relevant acupoints include Liangqiu (ST34), Dubi (ST35), Zusanli (ST36), Shanglian (EX-LE9), Xiaolian (EX-LE10), Jiexi (ST41), Taichong (LR3), Yanglingquan (GB34), Jieggu (GB39), Kunlun (BL60), Yinlingquan (SP9), Sanyinjiao (SP6), Fuliu (KI7), Ran Gu (KI2), Yongquan (KI1), Chengshan (BL57), and Shugu (BL65), totaling eighteen acupoints. Old methods often included Baihui (GV20) and Fengfu (GV16), along with Back-Shu and Front-Mu points of the Zang-Fu organs. However, recent practitioners report that these induce upward Qi movement, so they are avoided unless Qi does not rise abnormally. In critical cases where the disease is established and difficult to save, all these points must be treated.

The eight points located one fen away from the tips of the ten toes on both feet (totaling sixteen points? Text says "two feet total eight points", likely referring to specific pairs or a typo in source, but text says "Ba Chong") are named "Ba Chong" (Eight Rushes) by Cao Shi, effective for descending Qi. The tips of the ten toes are named Qiduan (Qi Endings); moxibustate 3 Zhuang daily using Dashen Yao (Great Spirit Ritual/Method). Ba Chong can be moxibustated with 7 Zhuang daily until Qi descends, then stop. When moxibustating Ba Chong, the moxa cones must be made small.
