Is there a high chance that Changzhou Railway Technical School will be recruited into the Railway Bureau?

Not big. The Railway Bureau generally recruits people with a bachelor's degree or above, and there are hundreds of thousands of people applying for the job, so the chances are slim. Changzhou, referred to as "Chang", also known as Dragon City, is a prefecture-level city in Jiangsu Province. It is one of the central cities in the Yangtze River Delta region of China approved by the State Council, an advanced manufacturing base and a famous cultural tourism city.
