I want to find a part-time job in Zhengzhou during the summer vacation. Are there any reliable intermediary companies? Is the recruitment information in the same city recruitment and Zhilian recruitment reliable? I won't say whether it is reliable or not, but what I know is that the green network of green culture media is the most reliable. Its predecessor was the first award-winning project for college students' entrepreneurship in Henan Province. The recruitment information posted above is free, but you must have business qualifications and certificates to pass the audit. Some staff members go to their stores and companies in person before the release, so green grid is credible.
