And here's Dragon Claws:

Similar cast list. It was IMDB that clued me in that maybe they're the same movie.

Also Known As:
Dragon Claws
Secret Ninja (USA)
Secret Ninja, Roaring Tiger (Hong Kong: English title)

If you think they're the same, I would delete Dragon Claws and combine with Secret Ninja.

No, those are two different films. (Dragon Lee and Hwang Jang Lee made several films together.)

They are both Korean films. In the Korean Film Archive, Dragon Claws is here

and Secret Ninja, Roaring Tiger is here

(Of course, as always, the films were retitled after Godfrey Ho & Co. bought the international rights.)
