I come from Shandong and want to work in Shenzhen.

Like you, you can submit your resume on the website of Shenzhen local recruitment market first, and it should be no problem to go to the factory.

Someone called you. You can come here when you set the date. You are still short of talents. If you are not satisfied, you can temporarily live near the talent market. It's cheap, and there's a job-hunting room. You can live there.

People like you will have a job in a week, as long as you are willing to do it.
