Ok, Ok, I worked at Xuchang Xueyuan years ago. It was fine, but yes there will be some culture shock. The FAO has changed, I see, but when I was there, I was treated fairly and pay was on time, things got fixed if broken etc. The apartments were just outside the campus (separated by a fence) in a modern (now 7+ years old) apartment complex (estate). They were big and in good condition. The East Campus is where you will live and I don't know if the original West Campus is even still around. The students were perhaps my favorites in China, on the whole. Mostly farmers kids who hadn't ventured out to anywhere except to Xuchang to go to university. There were a couple of friendly Chinese teachers, but most of the teachers didn't seem to socialize any more than was contractually required, even with each other. (That was years ago.) The library construction was delayed a year or more because someone lost about a million RMB.
The East campus was built on the outskirts of town (very flat, suitable for bicycling) with other major projects and six-lane arterial streets. There was almost no traffic at that time, probably has built up by now. Horse-drawn wagons competed with those blue mini-trucks belching black smoke, Mercedes Benz sedans, tuk-tuks, buses, and everything else. Empty new construction everywhere. The bus was fairly convenient and it didn't take more than about 15 yuan by taxi to get into the heart of town. (Or a 40 minute walk).
The city itself is not much to look at, but has decent supermarkets (Pan Dong Lai was the biggest and only true supermarket at that time.) Canals run through and around with lovely lotuses (loti?) at times. Locals range from sophisticated to the spittin', scratchin', helloooooin' yahoos you read about in China. I remember a few unfriendly hellos but mainly they would hello to my face. Most locals were friendly. There were few foreigners (there's one more tech school with foreign teachers and some Indian (South Asian) business people. The city is just small enough to be able to wander the downtown in less than a day, but big enough to get lost in too. Lots of good local food, especially if you like noodles. Try the hui mian (broad noodle stew). There's a couple of McD and KFCs around if you miss food you never ate at home.
One advantage about Xuchang, if you get tired of the "small" Chinese city, is that it is on the main railway from Beijing to Guangzhou. And now it's on the G-train line (the new station for express trains appears to be very near the campus). So you can get away to Beijing or elsewhere conveniently if you need a break from feeling like you're in a fishbowl or want to shop for expensive groceries from home, etc.
