There should be a devil training camp or something in 20 days. I participated in it once in my freshman year, and it was not bad.
The cost is about 2000 to 3000, and classes are held all day. Arrange a break in the middle, or go out to play and interact.
When I was a freshman, I lived in the south campus of Shangda University, which was arranged by New Oriental. Accommodation is included in the tuition.
The class place is also in the South Campus of Shangda University.
I don't know what changes have taken place now, but the specific changes should not be great. You can visit Harbin New Oriental official website.
