How to publish recruitment information in the market?

For example, if the company is in Qingdao, you can enter "Qingdao Fair Network" on Baidu. After entering the page, the top four items are "classified information, fair community, recruitment, education and training". After clicking "Recruitment", there will be "Freelance Position" in the upper right corner of the page, and then you can continue to follow the prompts.
