It may be normal-bad for China overall, but of the notable schools in Changchun (Perfect English, Victoria, English First, etc.) it's easily the worst. At every other school with more than 5 foreign teachers, the majority have relatively positive things to say about their school.
Honestly, I like Changchun but it's not a destination most people have in mind when they come to China. If you're looking to come here specifically you'd be better off at another school though WECI won't kill ya. Otherwise, find a more reliable place. They lie to you at WECI about your contract hours, work location, travel, benefits... at my new school (just across the street) I've been treated honestly and with respect, and I'm quite happy.
