Is it a lie to enjoy learning the ocean?

I met one in Tianhe District, Guangzhou. A girl with vulgar makeup came to me for a part-time job, which was very polite. I briefly said, because I was in a hurry, I asked for her business card, which was about beauty and skin care, interpersonal relationship, makeup modeling and so on. Later, I repeatedly called to ask if I wanted to visit their company and so on. I'm enthusiastic anyway. There is no full name of the company on the business card, but there is Weibo, a sea of science and music. Later, I searched online and saw many comments saying that I had encountered the same thing. What was deceptive? I refused to pay the money and didn't want to waste time reading it. In fact, I don't think she is cheating, but she needs materials at her own expense for part-time job. However, this way of paying first and then paying wages is inevitably alarming. I suggest that students can learn about it, but they need to be cautious when it comes to paying money.
