Yeah, I do... because the police warned my wife and I that they are dirty. The education bureau warned my wife and I not to take them to court after not giving me classes even though I had an obvious case against them. They also bullied another school that was going to give me a visa after I refused to continue taking classes there; oh wait, they didn't give me any classes

Lately many airlines have had unspecified delays or it's often "due to traffic control." My wife said it's because the military gets full priority. Which isn't as bad as it sounds because usually they are responding to a natural disaster somewhere. That's what I tell myself when I get in a 3 am anyways ;).

This has happened before, but usually your school just has to clear the vacation first. Push come to shove they tell you to call in sick and obviously don't use your passport at the hotels.

Your school probably just pissed off the KCEL mafia that always bullies other schools since their management knows nothing else.

Nothing new, but still effective. If your school isn't doing something similar when teaching/previewing vocabulary then you should find a new school.

Save your money, and just search online for "mnemonics."

Traditionally people studying at private Chinese schools would come on a tourist visa. A few years ago the private schools themselves would even recommend it since many students didn't show up. Win for both since students could shop around when they arrived and not get stuck at some school with terrible management like KCEL.

But with the visa reforms I have no idea now. I know in the past the government occasionally stopped the practice, but usually only for a few months.
