扯着嗓子唱寂寞
[chĕ zhe săng zi chàng jì mò]
The direct translation of this is 'shouting at the top of the lungs in loneliness.' It expresses deep, sometimes uncontrolled sorrow through shouting songs. It reveals someone who is very good at singing yet feels alone. Maybe they find solace or therapy through loud singing in lonely times.
