Yes, to be precise, it is to promote credit cards, because it is free for people. You go to the company to report in the morning, and you can arrange your own time throughout the day, such as going to office buildings, dormitories, and factories. Ah wait, these places usually have people who sell credit cards, and then go to the company to report in the afternoon. You can sort out the cards you applied for during the day and hand them in, then you can get off work. The salary is also determined by the number of applications you apply for. If you apply for a card and pass the review, you will get a commission. However, doing this is quite hard, but it can also train people. I wish you success, come on!
