Recently many people begin to find jobs on internet. Instead of looking for a job in a personnel market or in the ads of newspapers or magazines a job hunter tends to look for a job on the Net.

There are many advantages that people take advantage of this modern scientific and technological product—Internet. Firstly it's very convenient. A job seeker can look for a job without bothering to get recommendation or wasting time at an employment exchange. Secondly it's quite simple. A job hunter can get a job by simply clicking the ads online and sending one's resume through an E-mail. Lastly it's fair for everyone can utilize this modern means to win his or her opportunities even if one fails to find a job.
In a word with the increasing popularity of Internet I think this new way of hunting for jobs will win favor among many job hunters in China.
