Someone told me that the translation of the chinese character ? is LAM and not NAM. As example Nam Wai-Lit would be Lam Wai-Lit.
Another example is Yammie Nam - Yammie Lam would be more correct:

http://en.wikipedia.org/wiki/Yammie_Lam

In the hkmdb the character is alternately translated with Lam and Nam (and correctly with "Lan" in Mandarin):

??? / (Lan Yi-Ping)

What you all think? Do we now change the NAM names?

Yes, but we must keep NAM as alias.

Spelling vs pronunciation!

This might partially explain it, N vs L in Cantonese: http://en.wikipedia.org/wiki/Hong_Kong_English#N.2FL
and elsewhere in China http://forum.wordreference.com/showthread.php?t=343346

And FWIW, HK-based companies like Yesasia, Buyoyo spell it Yammie Nam.
Her weibo is no help since she uses the Mandarin spelling.

Same with Wong Cho-Nam/Wong Cho-Lam, ???. I can never figure out which is 'more correct.'


Update - And here is how she is listed in the Hong Kong Performing Artistes Guild website:
YAMMIE LAM KIT HYING |???|??? (Inducted: 1993-12-12 , Actor )

I checked the HKFA and Yammie Nam/Lam is listed as LAM Kit-Ying:

http://ipac.hkfa.lcsd.gov.hk/ipac20/ipa ... ex=NAMEBRP

But some names are listed as NAM like Francis Nam and Nam Nai-Choi.

I see that it is not as easy as I thought to answer the question what is correct.

More examples of different use of the names:

On my DVD cover of FINAL COMBAT Yammie Nam is listed as NAM Kit-Ying
On the cover of my HK-DVD of SEVENTH CURSE Lam Nai-Choi is listed as NAM Nai-Choi
In the HKFA book SHAW SCREEN Lam Nai-Choi is listed as LAM Nai-Choi

If no one objects I change soon the main names

Nam Wai-Lit to Lan Wei-Lieh (like in the HKFA)
Yammie Nam to Yammie Lam (objections?)
Wong Cho-Nam to Wong Cho-Lam (in almost all credits he is listed with "Lam")

I not change Francis Nam because I always see his name listed as Nam on cover,...

Nam Wai-Lit to Lan Wei-Lieh (like in the HKFA)
Yammie Nam to Yammie Lam (objections?)
Wong Cho-Nam to Wong Cho-Lam (in almost all credits he is listed with "Lam"

Done.

By the way: added 3 images to Yammie Lam from GREED OF MAN (very good TV production released on DVD with english subtitles).
