The construction and operation of subway need a lot of human resources. Before the official opening of Metro Line 5, the operation of Xi 'an has gradually entered a mature stage, and the construction and operation of the subway need a lot of human resources. Therefore, in order to ensure the normal operation of the subway, Xi 'an Metro has been recruiting talents, including engineering construction, operation management, safety maintenance and other positions. In addition, with the continuous advancement of Xi 'an city construction and population growth, the urban traffic pressure is also increasing, and the opening of Xi 'an subway line 5 also makes it more convenient for citizens to travel, so it is very necessary and important to recruit more people to ensure the normal operation of the subway. Xi Metro Line 5 is a subway line operated by Xi Metro and officially opened on 202 1 1 8.
