Skilled above technology, can accomplish successive, coherent, nature finish many expiratory, inspiratory technologies, the behavioral technology that and ask oneself are finished independently breathes out slow to be sucked quickly (pursue as follows 3) .

Hold genu in the arms to float exercise
Bipod stands benthic, deep inspiratory hind, crouch below lower his head to hold genu in the arms, two genu stand by bosom as far as possible, chela palm pedal leaves benthic, into lower his head to hold genu in the arms tucked pose. The body wants to be loosened as far as possible, in floating naturally at water (pursue as follows 4) .
