It's been many years since I paid my airfare to China or to Oman or to Bangladesh or to Lebanon or to Myanmar. It has been a condition of my employment. There is a lot more of this than you imagine, pengyou.

The way you state it's been a condition of your employment is a bit mysterious. AFAIK, the ministry of manpower/recruiters in Oman, always pay for your airfare to go there and a holiday once a year. As for China, I have never heard of this, except perhaps for some very good private school jobs or non teaching jobs. Your last statement is also a little condescending, especially as you don't explain why.

You say you have an MA. Well most jobs requiring someone with an MA and Delta say, in China, don't normally give you all that you want. 20,000 rmb a month yes, but free digs and airfare, no. They may however give you an apartment allowance.
