Fatal Vacation

Revisited it to confirm an ID, added more images as well as replacing all the old ones with new square ones

An old matter: is the ID of the twins now sure? If yes I can add many more movies to them (unfortunately are in some movies only one of them).

Someone had added the roles to the DB, but I can take a look around the net and see if something pops up on their names.

From what I can tell, both actors does star in A Book of Heroes in the roles given in the DB, but I can only see Tang Keung-Mei credited in the credits, and he is credited as a production manager, will check and see if I can't find some more info, but there isn't much about them out there

If we have in "Fatal Vacation" two names who could be brothers (same family name) and one of that names is in the crew of another movie with the twins I say it would be a great coincidence if the names not belong to the twins.

Now I think we can trust for the moment the ID and if nobody objects I add the Tang names to the movies with the twins.
I can not add a name to movies with only one twin (Dragon Family,...), but I think it is the one who is crew member in movies (but no proof).

Added the twins to more movies.
