This is a huge university spread out over four different campuses in the capital city of the province.  Sometimes in the past foreign teachers have had to travel between all four of the campuses to deliver their lectures.  Additionally, you very, very, very specifically need to ask the school on which campus you will be living.  In the past, the teachers were scattered all over the place -- and some of the apartments were great, perhaps the ones in the pictures that you have been shown, and the other older apartments were dreadful.  This is one question that really begs answer. 

Next, it's a very solid university that is for sure.  You will not be teaching the dumb-dumbs.  They are nearly all science and engineering majors and good ones at that with ONE exception :  if you are assigned to what used to be the Hebei Textile College, which is now part of the Uni, well, those students there are not the brightest bulbs in the universe by any means and you will need all of your resources at hand.  The other students are just great.

As for the capital city of the province, you will have a good time.  It's got everything that you need and more.  The rest of the province borders on the poorer side of life in China but the capital city is just great.  You can live as Western a lifestyle there as you wish or as Chinese a lifestyle there because all of the amenities are in place.

Additionally, it is a major, major railway hub and you can have easy access to the rest of the country.  There is an airport but it is of medium-size rank.

All the best to you!
