C1446 Confusion

I couldn't help but wonder, why would Sun Dongkai be so anxious to promote Cao Li? As the number of jobs in the group committee is fixed, the number of jobs are now full, how can Cao Li be promoted into the team?

Also, according to the rules for promotion of cadres, Cao Li did not have much time left in her term of office. Unless she broke the rules, she would not be able to be promoted either
