CROSSED SWORDS 1-2 were once also called PLEDGE OF THE TWIN BLADES 1-2 in the database:

https://hkmdb.com/db/movies/view.mhtml? ... ay_set=eng

In the meanwhile the titles PLEDGE OF THE TWIN BLADES 1-2 have been moved from the CROSSED SWORDS-Series to the THREE WILD BEAUTIES-Series:

When I checked the title "Pledge of the Twin Blades" in HKFA, I found all four above mentioned movies.
This looks a lot like a mistake in HKFA and the reason for the alias moving.
As "Pledge of the Twin Blades" can be viewed as a translation of 雙劍盟, I suggest to move back the aliases to the CROSSED SWORDS-Series.

Unless I hear otherwise (via email, not here), I or Chen Hung Lieh will change these back in a few days.

This thread serves as a reminder - every editor here without exception needs to follow the rules - especially the rules on changing existing data. (And I apply this rule to myself as well.)

I am going to be closely auditing the change log for the past 6-8 months. If I see a change or deletion in the log without a corresponding post here, I will be contacting you for an explanation.
