How many papers or periodicals of what grade do you need to evaluate the intermediate title of mechanical maintenance in Jilin City? Is there a time limit for publication?
If there are not so many requirements for the intermediate level, it is generally enough to publish papers at or above the provincial level 1.

If you are not at ease, you can send core journals, which will definitely be enough.

The publication time can be any periodical within 5 years of your evaluation of professional titles and submission of materials.

For example, this year's intermediate level evaluation, papers published after 20 1 1 year can be used.
