Dungong is one of the most commonly used bows in Erhu. Its symbol is "▼", which is written above the note (it is two different bowing techniques from jumping bow "▽"). The "pause" of the pause bow means pause, and it is a bowing method that makes a pause between the notes. Dun bow relies on the agile movements of the fingers to make the bow hair on the string alternately tighten and loosen, and at the same time cooperate with the pulling and pushing motion of the bow to make a short, elastic sound. Its actual pronunciation takes only half the duration of the note, and the other half duration is rest.

When playing an external string bow, the right hand is like a screwdriver, turning it slightly and quickly to the left (the direction of loosening the screw), so that the thumb will exert a force on the bow shaft, and at the same time, the middle finger should also push the bow shaft outward. , so that the bow hair sticks to the outer string, and cooperates with the short pulling and pushing movement of the bow to make a sound. When the sound is made, the bow should immediately stop moving, the right hand should be restored and relaxed, so that the bow hair floats on the string (not leaving the string), and the sound stops, thus completing the bowing action of an outer string.

When playing the inner string bow, use the middle finger and ring finger of the right hand to elastically "hook" the bow hair inward to make it stick to the inner string, and at the same time cooperate with the push-pull movement of the short part of the bow to produce sound. At the moment when the sound is made, the bow stops immediately, the middle and ring fingers relax, so that the bow hair floats on the string, and the sound stops, thus completing a bowing action of the inner string. When changing the strings of the bow, the bow should always run straight and rely entirely on the agile movements of the fingers to change the direction of the bow hair.

When playing the bow, keep in mind:

1. The wrist should be straight, and should not be bent inward or outwardly extended.

2. The right arm should be kept naturally relaxed, not tense and stiff.

3. The bow can only move left and right, and there cannot be up and down movements similar to hitting, so as to avoid noise from the drum.

There are two types of bows: "Fenton bow" and "Lianton bow". Fenton bow is to play one pause with one bow, and is usually played with the middle bow; Liandon bow is to play two or more pauses in one bow, and at most twenty or thirty pauses can be played. The medium-speed lianton bow is similar to the fenton bow in the playing method, the only difference is that after completing a pause action, the lianton bow has to play the second, third, and even more with the same bow direction. Pause. The fast lianton bow is also called "flying bow". It is different from the medium-speed lianton bow in its playing method. It relies on the right arm to play the strum in a very tense state.

Breaking down the action of the fast Lianton bow, it can also be understood as a combination of an approximate trembling bow and a pulling bow (the case of using a pushing bow is rare). When playing a fast continuous bow, the whole right arm should be in a relatively tense state, and while the bow is trembling, it is pulled out (or pushed in) to play a continuous fast bow. The key is to shake the bow evenly, draw the bow (or push the bow) stably, the speed ratio of the two should be appropriate, and the finger-pressing action of the left hand should be tacitly coordinated with it.

There are two things to keep in mind when playing the Lenton bow:

1. Allocate the bows reasonably so that each pause can have an effective bow of equal length. Avoid using too many bows for the front pauses and not enough bows for the latter ones.

2. If there are many slurs in a bow, be sure to push (or pull) the bow to the root (or tip) of the bow in the previous bow, in order to obtain as many effective bow segments as possible.

Erhu learners are prone to the following three problems in bowing:

1. When playing the bow, the bow is raised upwards, adding a "click, click" noise to the bow.

2. The right hand does not relax after the pronunciation, which causes the bow hair to oppress the strings and stop the reverberation, so the bow played in this way lacks elasticity.

3. Pronunciation is too long, which confuses the bow with the sustain.
