The key to circulating ventilation is that the connection between the new air and the residual air must be soft and smooth, leaving no traces.

The main process is: normal exhalation → expansion of the mouth to store residual air (the shape of the mouth is the same as the pinyin O sound, the base of the tongue is retracted, and the Adam’s apple is positioned downward) → the base of the tongue is inhaled = the rapid inhalation through the nose = the support point is moved down → the breath connection is raised → normal Exhale. The key step is to move the support point of the diaphragm down to the step of lifting the breath. This step will affect whether the connection between the fresh air and the residual air has traces and whether it is smooth. When the base of the tongue sends air and inhales quickly and sinks the breath (same as deep breathing, the position of the support point is lowered, the pressure in the lower abdomen increases, the waist expands), and then the breath is quickly raised (through the pressure in the lower abdomen), pay attention to the process of breath lifting should be smooth and smooth, otherwise the breath It is easy to have a sense of interruption or sudden strength. After the breath is successfully connected, it will be transferred to normal exhalation. Usually, you need to take a breath when the breath is more than halfway through, and if one breath is not enough, you can take several breaths in a row to meet the breath of the music, but the music must be uninterrupted, and the music must not be suddenly strong or weak. situation should be consistent.

It is not easy to master this point, you need to experience it repeatedly, find the feeling, and fix the found feeling through a lot of training to form a habit, so that the circulation can be used freely.
