Whether or not to pay depends on the size of your company. Small companies pay more, and big companies will come to you. Contact the student employment guidance center in Guang Mei or Jinan University. Generally speaking, as long as you are a regular company, it is ok for them to recommend one or two, but by this time, people have almost found a job. Maybe you can only enroll students at school first.
But how much can you earn? Haha, I can recommend my classmates. Ha ha.
