No info is available at this time as far as I know. However. should the agent's website reappear, you can apply.
I dunno if foreigner-friendly is the correct term. Youi can decide. Anyway, my advice is that you shouldn't leave your homeland to go there without a Z visa, a clean criminal background check, and credentials that are not bogus.

What you should know before signing a contract:

1 If you were to end up in a traditional Chinese house, your landlord will up the electricity bill. The amount depends on the city/county where the house is. Suppose the actual rate is 4.5 Mao/KwHr. You can expect to be charged anything between 6 Mao and 9 Mao. Don't believe anyone who tells you it's the actual rate, or some kind of penalty for the home using a great deal of electricity. I think you should ask the agent to reimburse the difference between the two rates. Expect the true rate to vary between 100 RMB AND 200 RMB per month depending on the season, and how much cooking you do.

2 The Chinese traditional house will most likely be in a poor area. It will probably be quite far from where you will be employed. You can ask for the reimbursement of taxi fares. Likely you'll have classes both morning and afternoon on some days. You can ask for the reimbursement of 2 return journeys by taxi on such a day so that you can return home at lunchtime for a rest.

3 Expect to experience traditional Chinese cuture in the poor area. This involves the locals showing great interest in you. They will most definitely ask your TA to tell them about you in detail. Ensure she never does that before it happens. Staring at you, trying to peek into your shopping bag to determine what you have bought, saying laowai to each other, all this will happen on a daily basis.

4 Ask your TA to obtain keys for you and discover the gate curfew times, and if it is possible to extend it for you on the odd occasion.

5 Should there be a thunderstorm, do not be surprised if the landlord turns off the electricity as a precaution. This can be infuriating if you're online. The apartment blocks nearby have electricity, while you don't.

6 As the company has lost many of its TAs, the new TAs will be inexperienced and newly graduated. It needs time to train them. The company does a good job in this respect. It even invites a foreign expert from Xi'an to assist with the training at the weekend. However, new TAs can be a pain in the neck.

7 You might get on great with your TA, but you might have trouble with her. It greatly depends on you. A good TA can be a valuable asset when planning the lesson and executing it each week. TAs are ten a penny, while FTs are rare. If she's a total twerp, complain and get her replaced.

8 A dirty half-clogged up twin tub in the house should be pointed out to the company. Ask them to arrange for it to be cleaned. If you neglect this, you won't be re-imbursed when it clogs up and has to be cleaned.

9 Probably the bed has no mattress. They won't buy a real mattress, but they will buy foam which does a good job.

10 New bed clothes, and pots and pans. Ask for them, and you will get them.

11 An infra red heater for winter. Ask, and you will get it.

12 Wily TAs. when you get mooncakes from the company free, the TA might criticise their quality. Tell her not to do so, as it's rude. If she asks you what she should do re completing class hour returns, ie fail to take account of cancelled classes, tell her to do as she thinks best. Even when she says the other foreigners ask their TAs to cheat the company in this way, ignore what she says.

13 Workplace. Public school students are generally better-behaved, more diligent, and more intelligent than those at private schools. Public schools are better in that there are more holiday breaks for FTs.

14 The Notorious Yuncheng Compound. I think anyone expected to live there should ask for an extra 500 RMB/ month salary increase as compensation for the very basic living conditions there. Or insist on a Chinese house, or an apartment.

15 The clause about disqualifying you from your travel allowance should you not wish to renew is unfair. Ask for it to be changed, and ask for 1000 RMB winter holiday allowance and 2000 RMB summer holiday allowance as well as at least 6000 RMB air fare allowance, to be paid in two instalments, at the end of each term. You might have to wait for 10 days after the 2nd term for those payments. This is to discourage FTs from pulling runners during Spring Festival.

16 The company does its best to keep the FTs happy, even those who leave. In this respect, they are very good.

17 Salary-wise, ask for 6000 RMB/month for 20 classes, plus 70 RMB for each overtime class.
