Is the recruitment information of China Railway 18th Bureau Group Fifth Engineering Co., Ltd. in the market really true?

I'm from the Human Resources Department of China Railway 18th Bureau Group Fifth Engineering Co., Ltd., and we don't have online recruitment. Our full-time employees are all recruited by the 18th Bureau Group Company, and generally only fresh college graduates are recruited. We have no authority (not only our five companies, but all the companies under the 18th Bureau have no authority), but we only have the authority to recruit internal children and contract workers. The number given upstairs is 022-252 16585, but we can't get you by phone ~ ~

All online (especially in the market) 18 recruitment of 5 companies is a liar! ! !
