Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
john wong » john song, john bonn
wang anh » dang anh, wang yan, wang all
tuan hua » tan hua, tuan vu, yuan hui
yan john » ryan john, gain john, tian john
wong sam » wong sau, wong lai, kong sar
hua ren » hua chen

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang anh) OR (wang yang)) tuan hua ren yan john wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang anh) OR (wang yang)) tuan hua ren yan john wong sam ;*.
