The shape, materials, and craftsmanship of Yehu are similar to those of Qinqiang Banhu. It's just that the piano bar is slightly thinner and shorter, with a total length of 67 cm, and is made of hardwoods such as mahogany.

Yehu often uses small shells as horses, as well as bamboo horses. Set two pegs, the strings are slightly thinner than the banhu strings, and play between the two strings with a ponytail bow.

The headstock and stem are made of a piece of hardwood, mostly mahogany or rosewood. The top headstock has a flat top, a crescent shape or is carved with a dragon head. Two shafts are placed horizontally on the upper end of the piano bar. The pegs are made of mahogany or boxwood, in the shape of a cone or hammer. The shaft handle is engraved with straight petal patterns. The rod is long, mostly cylindrical, but also semi-cylindrical (flat in the front and round in the back).

There is a bridge in the center of the panel. Traditionally, small shells were used to make horses. Later, bamboo bridge-shaped bridges were used. In Fuzhou, paper rolls were also used to make horses. Zhang has two silk strings. The qin bow is made of thin bamboo rods, and the two ends are tied with horsetails as bow hairs, and the bow length is 60 cm.
