In most cases, the erhu bow is pushed.

One of the four elements of music is the strength of the sound. Each measure in a musical work has a strong or weak point, and each piece has a climax and corresponding ordinary and weak parts.

According to the natural law of erhu bowing, the force of drawing the bow is generally stronger than that of pushing the bow (except for Jinghu, the bow of Jinghu holding the qin is special, and the force of pushing the bow is stronger than that of pulling the bow). Generally, for music that starts with a strong tone, the erhu uses a bow. Pieces that start with a weak note, start with a bow push. Pieces that start in syncopation also start with a bow push. The end of each measure is an upbeat, and usually the erhu also uses a bow push. But if the music starts with a forced, and there is a longer legato in the back, in order to highlight the strength of the legato, the bow is also used at the beginning. The ending part of the music is basically weakened, so it is more common for erhu to end with a bow.

The left half of the erhu bow is weaker, while the right half of the bow is stronger. Many pieces, especially the erhu solo, end with a pitch at the end, that is, the moment it is weak to the end, it suddenly becomes stronger. The bow was also transported to the right half of the bow, and it was suddenly pushed hard, which produced that effect.

Many solo pieces have relatively long ending notes and strong dynamics, making it pale and powerless to draw or push the bow. In order to highlight this effect, more bows are used.
