Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
she chang » shen chang, see change, lee chang
kwok wong » kok wing
yang van » yang fan, yang dean, trang van
van than » van thanh, van phan, van ham
than she » khan sher, than one, than we
won wong » hon kwong, john wong

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang van than she chang ((won wong) OR (kwok wong)) yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang van than she chang ((won wong) OR (kwok wong)) yue ;*".
