1. The main error is: incomplete composition!

Yes . . , which belongs to the sign of prepositional adverbial.

But this sentence lacks a subject after the prepositional adverbial.

The main structure of the whole sentence is: in. . Organize training. It should be: "yes. . Chinese, (subject). . . "

2. Secondary error: duplicate 1

Delete "a series of trainings" at the end of the sentence.

However, this change is not comfortable. It is better to write a series of trainings such as key counseling report, classified cancellation audit, personal quota management system and administrative licensing law.

-So, that's right.
