thuc va » thuc vat, thuc dan, thuc day
hieu ve » hieu va, hieu van
vu dai » vi dai, va dai, vu hai
ve nam » he nam, va nam, le nam
vu san » va san, vu ban
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((vu dai) or (vu san)) ky nang x hoi. hieu ve nam thuc va ((thanh di) OR (thanh do)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu dai) OR (vu san)) ky nang x hoi. hieu ve nam thuc va ((thanh di) OR (thanh do)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu dai) or (vu san)) ky nang x hoi. hieu ve nam thuc va ((thanh di) OR (thanh do)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((vu dai) or (vu san)) ky nang x hoi. hieu ve nam thuc va ((thanh di) OR (thanh do)) cua te*.
