Hong Kong naming conventions are pretty much the same as Korean naming conventions, with the addition of the western name.  Hong Kong, being a former British colony, required English translations to their films.  Many of the actors, actresses and crew adopted an English name to go along with their Chinese one.  This, of course, lead to multiple credits for the same actor.

There are two famous actors named Tony Leung.  Sometimes they are credited that way, but more often they go by their English name and Chinese name combined: Tony Leung Chiu-Wai and Tony Leung Ka-Fai (sometimes with the dash in their Chinese given name, sometimes without).

Some only go by the Western name (at least, they do when credited using Western characters).  Jackie Chan and Jet Li are two famous examples (though they are also credited in Chinese characters under their proper Chinese name).  Actor Andy Lau is rarely credited as Andy Lau Tak-Wah (and I don't think I've ever seen him credited as Lau Tak-Wah).  Director Andrew Lau is rarely credited as Andrew Lau Wai-Keung or Lau Wai-Keung.  Actor Ngai Sing moved to the US and changed his name to Collin Chou (his real Taiwanese name was Chou Siu-Lun), which he now uses exclusively.  Sometimes the name isn't even consistent, as Johnnie To was sometimes credited as Johnny To in his earlier films.

Some actors used an English name for a brief time.  Lau Ching-Wan tried the name Sean Lau, then dropped it.  Even Chow Yun-Fat went by an English name for a brief time: Aman Chow.

There are also the naming conventions of Mandarin names versus Cantonese names.  Take Lau Kar-Leung.  When he was an action choreographer and director at Shaw Brothers, they used the Mandarin version of his name: Liu Chia-Liang.  In the later years, he went by his Cantonese name: Lau Kar-Leung.  His "brother" Gordon Liu, can be found under his western name Gordon Liu, his Mandarin name Liu Chia-Hui, his Cantonese name Lau Kar-Fei, or a combination of his western name and Chinese names.

Like Korean and Japanese names, you have a translation problem, which means that the name might not always be consistent.  Take Gordon Liu: glancing at HKMDB, they list additional aliases as Lau Ga-Fai,  Lau Kir-Fai,  Lau Kar-Fai,  Liu Jia-Hui,  Lau Ka-Fei and  Liu Chia-Fai.  This is not uncommon in films in the '70s and '80s.

As you can see, Hong Kong naming conventions are not simple (though it isn't difficult to standardize).

I am afraid I have to disagree, there is nothing like a middle name in Germany, only the possibility to have more than one first name.

sugarjoe,

Could you explain how you are familiar with German naming convention?  We have 3 members from Germany who seem to more or less agree with SpaceFreakMicha regarding middle names in Germany.

I am German and live in the UK, I hope that qualifies... 

Please look up a German id card or any other German official form, nowhere would you find the field 'middlename' but only 'given names'. This goes along with the Dutch modell as described by Eric.

Eric,

Thanks for the explanation.  Any corroboration or rebuttals from our German members?

I am Eric and I am from the Netherlands...    Of course you meant Sugarjoe...

It all depends a bit the way you translate. If you equate the given names with first names, then there are no middle names. But note the plural, it is not the same as a single (or for that matter double) word first name USA-style.
If you translate American style the first given name to first name, the rest would become middle names.

Translating "voornaam" (NL), "Vorname" (D) litterally means names in front (of the surname). Translating it as "first" is just a close approximation to make sure the listener/reader basically understands. But translating it to "given names" only is far more correct.

That all said, I can safely say (I guess), that for NorthWest Europe (Germany, Netherlands, Belgium, I am not sure about the Nordic countries) the first of the given names does not have a special/formalised position. It may be your calling name, but that may be something else too.

This is a fascinating post, green arrow to you Xradman for a great idea! 

As for the UK, naming conventions seem follow a family, rather than any "national" convention.
But the basic structure is the same.

We have a first name (or names), an optional middle name (or names), and the last name (or names!) which is your family or surname.
The one thing about UK names is that we do like doubling things up - which is why I wrote "names" so many times above.
Double-barrelled first names although not common are possible, I've never heard of a double-barrelled middle name but certainly a person can be given multiple middle names.
The creation of double-barrelled surnames is not that common these days, usually only existing because they've been used by that family for years. But they were commonly created when two well-off families would inter-marry and neither wanted to lose status, so both surnames were used.
Traditonally when a woman marries she loses her maiden name and takes her husband's name. There are some situations when she would continue to use her maiden name in common use, but legally her name would be his. I've never heard of a woman moving her maiden name to become a middle name in the UK.
Mother's maiden names will sometimes be passed down to children as middle names but at that point it ceases to be a family name.
As for that "family" comment at the top, this is where it gets complicated. Families in the UK can have their own traditional naming convention. For example in my family the men are given a first and a middle name, but in general use their middle name not their first name, whereas the women will use their first name and usually won't be given a middle name at all.

I think I've just confused myself now!

Right, in germany there is no word like "middle name".

US: first name / middle name / last name

Germany: first name / second name / last name

To elaborate on that:
In German, it is not called "first name", but "Vorname", which translates to "forename" or "given name".
The US middle name is called "zweiter Vorname" ("second forename").
If you look here, you can see, that "middle name" translates to "zweiter Vorname".

Please note that our official documents don't even have space for a seperate middle name (I don't have one anyway), also note that the official english terms on this german document are "surname" and "given names".

(first: ID card, second: driver's license) - I edited the picture to make it useless for anything but looking at it:

Disagree. If you are named Gerd Hans Heinz Meier what would that make Heinz?

Third forename
Would also fall in middle name field (for Profiler purposes).

Sorry, but before this is officially clarified for me (and therefor for profiler purposes) it would be

Gerd Hans Heinz//Meier

Your ID card does seem to have a space for something as noted by the blank entry in the name (red here)
IDD<<SCHRAMM<<KARSTEN<<<<<<<<<<<<<<<

There's also room on both cards for multiple given names though.
