Though i'm not under Ms. Liu, i know what she's doing coz i have friends working under her. My friends are just waiting for their contract to end so they can escape from Ms. Liu's chain. I have seen their appartments, and for goodness sake, i can't describe how bad it is. Ms. Liu even doesn't dare to talk to you coz she thinks you're just her poor employee, that's how arrogant she is.
It's true, she won't process the visa of her teachers coz she doesn't have a permit to do that.
If you'll hear of the name Ms. Liu of Tonghua city Jilin province, or Meheiko City jilin province, beware she might sting you.
