Beijing bus recruits drivers and wants veterans. Why didn't anyone go?

There is too much pressure on Beijing public transport to recruit drivers, and no one wants veterans to go. Beijing Public Transport Group recruits customized bus drivers, and party member and veterans are preferred. The form of employment is to sign a labor contract, and no one wants to do it. There is a simple reason. Mental stress is too great. There used to be a conductor, but now he's gone. The conductor's job allows the driver to do it, but the salary does not increase.
