The Wong Brothers are members of the Portland Island Triads in 1998, and make an appearance in the side mission Wong Side of the Tracks in Grand Theft Auto: Liberty City Stories. It is possible that one or more of the members of the Wong family owns Mr. Wong's Launderette, which can be found in Liberty City in Grand Theft Auto III, GTA Liberty City Stories, and Grand Theft Auto IV because of the relations in the names.
It is possible for the brothers to die, as they may (though it's not required) be killed in the aforementioned mission.
