If you want to find a job, go directly to the company. How do you know someone is hiring? Go in and ask when you see the company? I don't know who to ask.
Check online first, and send some resumes on websites such as ChinaHR.com, Zhaopin.com, Worry-Free Future and 5 1job. If you have a phone number, write it down and call to introduce yourself. There will always be an opportunity for you to apply. Some newspapers also have recruitment information, so just pay more attention to it yourself. You can also pay attention to the time and place of your job fair and attend it.
