The tuner saved a bunch of second-hand stars. I won’t list them all here. Those who dare to hold concerts seriously can all sing pretty well. Those who only release albums and singles but never hold concerts are basically mixed. I still miss those singers in Hong Kong, who basically debuted from street performances to talent shows. Those who are good at it all give concerts, and those who are not good at it occasionally go out of their way to sing. It’s not like us bastards. I feel like without a tuner, the singing is not as good as mine.
