Hi there together,
and thanks for your discussion and important points.
The Chinese, in my understanding, says that the Lee family
would not allow "Jeet Kune Do" in the title, so it was changed.
(Quite understandable, as Ho Tsung-Tao or anyone else after
Bruce Lee could perform his style properly

So I think, the change of the entry to "Bruce Lee's Secret"
should be obvious then?
Besides I would have pointed out the simple physical proof
with the images uploaded: this lobby was sticked over with
"Story Of The Dragon" and also the Chinese title:

http://hkmdb.com/db/movies/image_detail ... ay_set=eng... and the poster here was reprinted, covering its former title
with some kind of repetetious background segment if you watch closely.
So, to me, it is obvious, "Bruce Lee's Secret" was there in the first place.
If the definition for a title as a main entry is with which title a movie started
in the cinemas in Hong Kong (this movie being nevertheless a Taiwan movie,
as Lan Tien Hung registered his company in Hong Kong only) ... then "Story
Of The Dragon" would be the right entry, although the original title wasn't
intended that way and posters already printed. Also, maybe it was shown
as "Bruce Lee's Secret" in Hong Kong first and some days, so that the Lee family
got knowledge of that and complained. Officially there is only a release date
source of "Story Of The Dragon" shown in Hong Kong.
