dong nan » dong yang, dong bin, dong cao
ya human » a human, das human, 2 human
gene yan » ren yan, see yan
jiu wong » jiu cong, ji won, kie wong
wong sau » wong sam, wong siu, wong shiu
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong nan) or (dong sin)) ya human ((gene yan) OR (gene bank)) jiu wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (dong sin)) ya human ((gene yan) OR (gene bank)) jiu wong sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (dong sin)) ya human ((gene yan) OR (gene bank)) jiu wong sau ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (dong sin)) ya human ((gene yan) OR (gene bank)) jiu wong sau ;*.
