What is "laruan"

The lāruǎn (拉阮; also spelled la ruan) is a relatively new Chinese string instrument blending the acoustics of the ruan with that of the Western cello. Its larger counterpart is the dalaruan, which corresponds to the double bass.

These musical instruments were created in the 20th century to be an alternative to other bowed bass register instruments used in Chinese orchestras, such as dihu, cello/double bass, gehu/ diyingehu, damatouqin/dimatouqin, and paqin/dapaqin. The China National Traditional Orchestra of Beijing is one of the few Chinese orchestras using this instrument.
