What does it mean to go to China Railway Third Bureau for an interview?

Recently, I got a beautiful anchor for Tik Tok. You can find someone who will go to China Railway Third Bureau for an interview tomorrow in the comments section. What exactly is this China Railway Third Bureau doing, which has caused so many netizens to boo. It turned out that the China Railway Third Bureau posted a recruitment information on the Internet. The recruitment target is a clerk, and the salary is 4000 yuan per month. Require good facial features, good figure, preferably just graduated from school, and even more outrageous address is in a hotel.
