They also work with local musicians and play a few local songs with Chinese folk instruments so audiences can gain a holistic understanding of Chinese music.

Apart from teaching in schools, the musicians have also worked with nursing homes in Denmark, experimenting with Chinese folk music as therapy to help treat Alzheimer's disease.

After receiving training from Alzheimer's disease experts, the Chinese musicians used folk instruments to perform classic Danish tunes that patients might have been familiar with from their childhood. Apart from yangqin, the musicians used a few other folk instruments such as the guqin and the pipa, both of which are plucked string instruments.

"Often after a half-hour session some of the people would be crying. In one case a man kept asking us all sorts of questions, and the carers told us that before we came he said barely a word."
