动乃数脉，见于关上下，无头尾，如豆大，厥厥动摇。仲景曰∶阴阳相搏名曰动，阳动则汗出，阴动则发热，形冷
恶寒，此三焦伤也。成无己曰∶阴阳相搏，则虚者动，故阳虚则阳动，阴虚则阴动。庞安常曰∶关前三分为阳，后三分
为阴，关位半阴半阳，故动随虚见。《脉诀》言∶寻之似有，举之还无，不离其处，不往不来，三关沉沉。含糊谬妄，
殊非动脉。詹氏言其形鼓动如钩、如毛者，尤谬。
〔体状诗〕动脉摇摇数在关，无头无尾豆形团。其原本是阴阳搏，虚者摇兮胜者安。
〔主病诗〕动脉专司痛与惊，汗因阳动热因阴。或为泄痢拘挛病，男子亡精女子崩。仲景曰∶动则为痛为惊。《素
问》曰∶阴虚阳搏，谓之崩。又曰∶妇人手少阴脉动甚者，妊子也。
促脉，来去数，时一止复来（《脉经》）。如蹶之趣，徐疾不常（黎氏）。《脉经》但言数而止为促，《脉诀》乃云∶并
居寸口，不言时止者，谬矣。数止为促，缓止为结，何独寸口哉！
〔体状诗〕促脉数而时一止，此为阳极欲亡阴。三焦郁火炎炎盛，进必无生退可生。
〔相类诗〕见代脉。
〔主病诗〕促脉惟将火病医，其因有五细推之。时时喘咳皆痰积，或发狂斑与毒疽。促主阳盛之病。促、结之因，
皆有气、血、痰、饮、食五者之别。一有留滞，则脉必见止也。
The Dong (Moving) pulse is a type of Shu (Rapid) pulse, appearing at the Guan position and its vicinity, without distinct head or tail boundaries. It is as large as a bean and exhibits vigorous, oscillating movement. Zhang Zhongjing stated: "When Yin and Yang contend with each other, it is called Moving. If Yang moves, sweating occurs; if Yin moves, fever ensues, accompanied by coldness of the body and aversion to cold; this indicates injury to the San Jiao (Triple Burner)." Cheng Wuji stated: "When Yin and Yang contend, the deficient aspect becomes active. Thus, Yang deficiency leads to Yang moving, and Yin deficiency leads to Yin moving." Pang Anchang stated: "The three fen anterior to the Guan position belong to Yang, and the three fen posterior belong to Yin. The Guan position itself is half-Yin and half-Yang; therefore, the Moving pulse appears according to the site of deficiency." The Mai Jue (Pulse Classic) states: "Upon light palpation, it seems present; upon heavy pressure, it vanishes. It remains in its place, neither coming nor going, with the three Guan positions feeling deep and still." This description is vague and erroneous, completely failing to describe the Moving pulse. Zhan's description of the pulse form beating like a hook or hair is even more absurd.
[Body Form Poem] The Moving pulse trembles rapidly at the Guan position, lacking head or tail, forming a bean-like cluster. Its origin lies in the contention of Yin and Yang; the deficient side trembles while the strong side remains stable.
[Main Disease Poem] The Moving pulse exclusively governs pain and fright. Sweating results from Yang moving, and fever from Yin moving. It may also indicate diarrhea, dysentery, or muscle spasms. In men, it signifies loss of essence; in women, it signifies metrorrhagia (bing). Zhang Zhongjing stated: "A Moving pulse indicates pain and fright." The Su Wen (Plain Questions) stated: "Yin deficiency with vigorous Yang pulsation is called Bing." It also stated: "If the Hand-Shaoyin pulse in women moves vigorously, it indicates pregnancy."
The Cu (Surging) pulse comes and goes rapidly, occasionally pausing before resuming (from the Mai Jing/Pulse Classic). It resembles someone stumbling while running hastily, with speed varying irregularly (as described by Li). The Mai Jing only states that a rapid pulse with pauses is Cu; however, the Mai Jue claims it appears simultaneously in the Cun (Inch) position without mentioning pauses, which is erroneous. A rapid pulse with pauses is Cu, whereas a slow pulse with pauses is Jie (Knotted); why should this apply only to the Cun position?
[Body Form Poem] The Cu pulse is rapid and occasionally pauses; this indicates Extreme Yang desiring to exhaust Yin. The Fire of Stagnation in the San Jiao burns fiercely; if the condition advances, there is no survival, but if it retreats, life can be preserved.
[Similar Pulse Poem] See Dai (Intermittent) Pulse.
[Main Disease Poem] The Cu pulse primarily treats diseases caused by Fire. Its causes are fivefold and require careful analysis. Frequent wheezing and coughing are due to phlegm accumulation; alternatively, it may manifest as mania, macules, or toxic sores and carbuncles. The Cu pulse indicates Excess-Yang conditions. Both Cu and Jie pulses arise from differences among Qi, Blood, Phlegm, Fluids, and Food retention. Any stagnation will inevitably result in pauses in the pulse.
