Can I go to Liuyang Lance Technology to recruit general workers myself? As a summer job, can I not go through an intermediary company?

Are you applying for a general job? You can.

Anyway, enterprises should employ people, who should they use and who should they not use? Moreover, they have to pay extra money through intermediary companies. If delivered to the door, they even saved the cost of recruitment.

But you only do summer jobs, so you have to ask their personnel. I suggest you don't rush to the door to apply for a job, but find their personnel contact number first, ask about the situation first, and then decide whether to go.
