The person who posted that WeChat Moment, an ID named Xiang Kun didn't recognize, must be one of the customers from the bar before.
However, he seems to have quite a number of friends, judging from the long list of replies under his post.
"Damn! I thought Huang Shao had found new heavenly voices... my ears! Huang Shao, don't your conscience hurt..."
"Just a couple of drinks and he ends up like this?"
"What on earth is he singing? How come nobody in the bar went up to hit him?"
"Haha, you see the body of this guy, would you dare to confront him? It's clear no one could take him on!"
"Can this be the pub owner? He runs the pub just to have a free audience?"
"Huang Shao, it's fine if you're suffering yourself, don't make us suffer by posting this."
"Why do I see the girl in the lower left corner of the video seeming so engrossed and focused? Is she the girlfriend of that bald guy?"
