Why do people play suona after death?

It is a custom to play suona to express memory of the deceased.

Suona: Suona is a folk musical instrument. It is convenient, economical and practical. Even poor people in ancient times could afford it. In addition, the more economical instruments include flute, xiao and erhu. Among these instruments, only the sound of erhu and suona can express sad mood, but

It is not convenient to play the erhu while walking during the burial, so only the suona is the most suitable, and the suona can express the tragic, indignant, and sad feelings of the family members of the deceased.

Funeral songs: Traditional ones include "Tomb Beating Tune" and "Widow Visiting the Grave".
