Tongli (HT5) is located posterior to the wrist crease, one cun proximal to the transverse crease of the wrist. If a patient desires to speak but cannot produce sound, and experiences restlessness (Ao Nu) and palpitations (Zheng Chong), excess patterns manifest as heaviness in the four limbs and redness of the head, cheeks, and face. If the voice is normal but there is frequent yawning, or if there is throat obstruction (Hou Bi) with difficulty in breathing; deficiency patterns manifest as inability to eat, sudden loss of voice (Bao Yin), and a lackluster complexion. A filiform needle should be inserted slightly, and one will believe in its miraculous efficacy.

Lieque (LU7) is located superior to the radial side of the wrist. The location method involves crossing both hands, where the point lies in the gap between the bone and tendon at the tip of the index finger. It is effective for treating hemicephalic headache, generalized wind-bi numbness, frequent accumulation of phlegm-saliva obstructing upwards, and trismus (mouth locked shut). If one understands tonification and sedation techniques, recovery follows immediately upon needling.

[Note] Lieque (LU7) is located 1.5 cun superior to the radial wrist crease on the dorsal-radial side. When the hands are crossed, it lies in the depression between the bone and tendon at the end of the index finger. It treats symptoms such as hemicephalic headache, generalized wind-bi numbness, phlegm and qi obstruction, and trismus. Needle 0.2 cun, retain for three breaths, moxa 3 moxibustion cones.

The principle of sitting orientation for acupuncture and moxibustion in the four seasons should follow natural laws. The directions of East, South, West, North, and the four intermediate corners are used to welcome the vital qi (Sheng Qi), which originates from Heaven.

[Note] Regarding the principles of avoidance for sitting orientation during acupuncture and moxibustion, *Yixue Rumen* states: "In spring, sit facing west; in summer, sit facing north; in autumn, sit facing east; in winter, sit facing south." These orientations turn one's back to the vital qi of the four seasons and should not be followed. Instead, one should face East in spring, South in summer, West in autumn, and North in winter. During the four months when Earth is prosperous, face the four intermediate corners to welcome the vital qi. This conforms to heavenly principles and follows nature naturally.

When locating points, the body must be upright whether sitting, lying, or standing. Use moxa cones made from Qizhou mugwort (*Artemisia argyi*) shaped like fire pearls. In ancient times, eight types of wood fires were taboo for moxibustion; currently, using a single incense stick is a common and convenient method.

[Note] For all moxibustion methods, if points are located while sitting, moxa is applied while sitting; if located while lying, apply while lying; if located while standing, apply while standing. The limbs and torso must be kept straight and not tilted, otherwise the points will not be accurate. The mugwort used for the cones must be Qizhou mugwort. The mugwort leaves should be dry, pounded in a mortar to remove dust and debris, and formed into firm cones. Place the cone on the point and secure it with green onion juice. In ancient times, fire was gathered using a crystal lens reflecting sunlight to ignite the moxa. Fires from pine, cypress, zanthoxylum, tangerine, elm, jujube, mulberry, and bamboo were taboo. Currently, only incense sticks are used to burn the moxa, which is also a widely accepted and convenient method.
