Some ads for Yuncheng offer far less.

One example:

Job code: SXYCT-01,
- Location:Yuncheng, Shanxi Province
- Start date: ASAP
- School type: Public school
- Age level: 3-18 years old
- Workload: 20 classes /week
- Salary:RMB 5000-6500
- Airfare: 5000 RMB
- Housing: Free apartment (not shared)
- Holidays: Public holidays + winter and summer vacation
- Two days off at weekend
- Working visa and insurance provided
- Native speakers required

Note: 5000 rmb ;pw end salary, 5000 airfare/bonus, no mention of travel money.

Note: No mention that Public holidays are PAID. They won't be.

In this case, the recruiter took the difference, pocked the travel money, lower salary each month, and the 1000 to 3000 in missing airfare.
