Jiangsu Nanjing overseas labor agency fee problem! ! ! !

My wife went to Singapore, paid an agency fee of 33,000 yuan, and changed 200 yuan Singapore dollars at home, which cost 1000 yuan. It cost 300 yuan for physical examination in China, and 35,600 yuan before and after buying something. As a sewing worker, the monthly salary ranges from 5000 to 7000. Accommodation plus meals will be deducted 1000, and there are other expenses. How much is left? I dare not spend money at ordinary times.
