Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
yang yang » wang yang, wang yan
than wong » thang long, than one, than done
chan eng » chan fong, chan kang, chan ming
iii gene » iii rene, iii gender, iii genome
one than » money than, more than, one thing
wong sam » wong sau, wong lai, kong sar
li gene » i gene, l1 gene, lof gene

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yuan chang) or (chan eng))) or (yang yang)) ling ((li gene) OR (iii gene)) one than wong sam ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan chang) OR (chan eng))) OR (yang yang)) ling ((li gene) OR (iii gene)) one than wong sam ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan chang) or (chan eng))) or (yang yang)) ling ((li gene) OR (iii gene)) one than wong sam ;*".
