Without warning, the teachers ask students from each country to take the microphone and explain to everyone their reasons for coming to Harbin.

我敢打賭，在Tom Waits發掘它當幕後支援前你從來沒有聽說過斯特羅小提琴！無論如何，1920年代末前它採用了一個大型金屬喇叭諧振器來代替木製音箱，以便它可以更好地被錄音設備收音。

I bet you'd never heard of a Stroh violin before Tom Waits dug it back up! Anyway, it used a large metal horn as its resonator instead of a wooden box so it could be picked up better by recording equipment before the late 1920s.
