Gokusen

Both dramas are about a school full of yankees! If you like fighting and shouting, you will love it ;)

The film shows Chan Ho Nam , Chicken Chiu and their friends being recruited by Uncle Bee and joining the "Hung Hing" triad.

Both drama show female teachers helping their students

There's no angry mom in Gokusen but there is some organized crime involved but more like Han Gong Ju-style, there is a righteous teacher, a stupid vice principal and unruly students, but also some rather preachy dialogues/monologues. Regardless, both are a fun watch with darker themes (Angry Mom is upfront with it, if not a bit gory at times while Gokusen is more careful, mostly if you care to think hard and long enough since Gokusen's premise relies more on comedy) as the students mature and grow through their actions.

Teachers with secret identities.
Yankee students.
Life lessons.

Both have the "Passionate young teacher" as the premise. Sawada and Kuma made an appearance in Yoiko no Mikata".

How Gokusen's teacher might have failed in an alternative world and evolved herself to become her opposite nature
