The steps that have changed from the basic steps by breaking the basic standard of the basic steps are collectively called "variation steps" and are the most basic standard steps after variation; we call the special requirements and standards that have been formed or that have been created differently from the basic standard of the basic steps in order to fulfill the variation steps in accordance with the basic standard as the "variation standards". We collectively refer to the special requirements and standards that are formed in accordance with the requirements of the "Basic Standard", or that result in a basic standard that is different from the basic step, as the "Variation Standard". The Three-Step Movement Series, Gold, Silver and Bronze Medal Moves and Fancy Steps have distinctive rhythmic characteristics in themselves. Among the 67 movements, except for the "Waist-supporting Series, the Ring Series and the Mirror Series" in the Movement Series (which use the hands as the rhythm), it should be said that the Cat Steps, Running Steps, Gold, Silver and Bronze Medal Moves and Fancy Steps are governed by the "Variation Standards". It should be said that the catwalk, gallop series and the gold, silver and bronze medals in the movement series and the fancy steps are absolutely influenced by the basic standard, and the most influential one should be the characteristic of "stepping" of the point step; even the "changeover step, forward step, backward step, and turnaround step" in the basic steps are all contrary to the basic standard. However, the steps of "shift step, forward progress, backward step, turn body step" are commonly found in the action series and the gold, silver and bronze medal actions and fancy steps, sometimes they completely replace the basic step and the push and pull start step. Such as the roc spreading wings, all the former progress; and the lion rolling embroidered ball is also the main former progress; and then such as adventure climbing cliff, sleeping beauty, cat step, etc., it is impossible to dance according to this basic standard. Therefore, although the "change of position step, forward progress, backward step, turn the body step" is based on the basic step, breaking the basic standard of mutation, according to the reason they should not be included in the basic step, but, it is precisely because of their widespread, universal existence in the action series and gold, silver, bronze medal action and fancy step action, we However, it is because of their widespread presence in the movement series and in the Gold, Silver and Bronze Medal and Fancy Dance movements that we are forced to include them in the basic steps.
