What is a Chinese musical instrument that is played with two sticks?

It is the "yangqin"

The yangqin is an East Asian folk instrument, also known as the yangqin, the beat zither, the beat zither, the fan zither, the bat zither, and the butterfly zither (almost universally known as "yangqin" in modern times), which is characterized as a percussion instrument and a stringed instrument, but is still classified as a "plucked instrument" in national orchestras. It has the characteristics of both percussion and stringed instruments, but it is still compiled as a "plucked instrument" in the national orchestra.

Playing--

The instrument is played by alternately striking the bamboo with both hands from left to right, or by striking a single note in unison in order to increase the volume. Striking the strings with the bare bamboo side (i.e., the side not covered by rubber skin) is called "anti-bamboo," which has a sharp sound like metal touching each other; "hooking" with the end of the bamboo creates the effect of plucked music. Yangqin has a long aftertone, which can be silenced by pressing the strings with your fingers. Wearing a "slide finger cover" can be played after the slide. In the national orchestra, it is located in the first row in front of the conductor, often playing harmony or arpeggio. It is also an important accompaniment for the solo pieces of Huqin and flute.

Effective string length for the bridge code left then a section of the strings by the left and right ends of the cover plate under the screws bolted, must be tuned with tools.

2, bridge code

Commonly used "five rows of code" yangqin from right to left known as the bass code, the left code, the code, the right code, chromatic code. There are also 3-row and 4-row bridges.

3, bamboo

Also known as the bamboo bamboo, bamboo keys, made of flexible bamboo, for the strings, commonly used in single-tone bamboo, single-tone bamboo, double-sided bamboo, double-tone bamboo and so on. The bamboo body is long and thin, and one end is flattened when held in the hand; the strings are hammered at one end, and one side is covered with rubber or other elastic materials. Yangqin's original stringing tool is a wooden mallet, the tone is more crisp than the bamboo.
