First, let's understand the basic playing technique of "single spit". In hulusi playing, the single spit is mainly used to express clear and coherent melodic lines, which is similar to the single note playing method of the flute. When practicing single spit, the staccato effect is produced mainly through the quick contact of the tip of the tongue with the roof of the mouth, forming each independent and clear note. In order to master the single vomiting technique, in addition to correct mouth shape and breath control, it is necessary to carry out a lot of basic scales and repeated practice of etudes to achieve a uniform, clear and smooth effect of each note.

When practicing double vomiting, it is necessary to quickly alternate the two actions of "vomiting" (represented by "T") and "library" (represented by "K"), that is, the tip of the tongue is quickly pressed against the roof of the mouth to make a "T" sound, and then the tongue quickly retract, so that the air impacting the bottom of the mouth makes a sound similar to "K", so as to form a coherent and fast double spit syllable. The mastery of the double vomiting technique also requires long-term and systematic training, especially the flexible control of the tongue muscles and the precise grasp of the use of breath.
