Perhaps you should try some spelling variations:
guifang yang » cuifen yang, huang yang
liang yang » liang ying, wang yang, huang yang
yang yang » wang yang, wang yan
hua irene » hua ren
kong sara » kong sar
yang tan » yang fan, yang dean, liang tan
tan kong » tan hong

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((liang yang) OR (guifang yang))) or (yang yang)) hua irene yang tan kong sara ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((liang yang) OR (guifang yang))) OR (yang yang)) hua irene yang tan kong sara ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((liang yang) OR (guifang yang))) or (yang yang)) hua irene yang tan kong sara ;*".
