Is there an age requirement for bar singers in Houhai, Beijing? 16 ok?

16 principle doesn't work. Actually, you can try ...

Those who sing well are not popular, and those with independent characteristics (such as voice, appearance, singing skills and arrangement) have more vitality. See the overall environment and style of the bar.

You can't make a lot of money. If you sing during the holiday, you might as well find a place with more people to fight guerrilla warfare and earn more money. If you don't want to show your face, bring a mask or wig for reference. The facts are all the same.
