I had an issue with a school in 2019 where I quit the school and after I got my final salary I left China.  I understand the school was upset because i was unable to cancel my residency permit.  Less than a year later I was able to get a work permit in Guiyang and had no problem getting a work permit for Shenzhen, Then this year I had applied for another work permit in Liaoning which is the province where the school i quit was and my application was denied.They said something that I was blacklisted. I would think that if i were blacklisted from working in China that from the time i quit the school I would be unable to get a work permit from anywhere in China.

     Would it be better when I apply for jobs in China not to state that  I had worked in China before when applying for the work permit and that I never had a residency permit? Since the last time I was in China I had to replace my passport due to damage. I anticipate that any information that they have on me would be linked to the passport number. Normally when I apply for jobs I would not include jobs that were either not relevant to the position I am applying for or that I did not stay at for at least 6 months. I anticipate that the issue i had was likely due to the fact that I had stated I had work for the previous employer which I quit from and gave them a copy of the  past residency permit. I also probably should not have tried to apply for a work permit in the same province.
