Its an underrated slice of life police drama with string of cases which are solved in a few episodes or less. It also shows the growth of different characters in a realistic trajectory. The veteran actors as masters of the younger cadets really steal the show in the drama. As a frontline worker myself i appreciate the arc of personal lives of the police officers, portraying as only human too. Yet society places higher expectations on them which will never change. The annoying characters are shown empathy and you get to see why they are the way they are (doesnt mean you will like them any more). Its a realistic portrayal of life and politics within a frontline service and further enhanced by the excellent acting skills of the veteran actors. Bai Lu and Xu Kai Cheng were believable but probably took a back seat when it came to comparing them with the vets.
