Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh ve » dinh ve, hanh ve, anh ve
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
tuc va » thuc va, truc va, duc va
sac ky » cac ky
va cam » va cham, va cac, va cao
ve ve » de ve, va ve, ke ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sac ky) OR (sai ky)) nang xa hoi. hieu va cam ((tuc va) or (tuc xa)) danh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) nang xa hoi. hieu va cam ((tuc va) OR (tuc xa)) danh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) nang xa hoi. hieu va cam ((tuc va) or (tuc xa)) danh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) nang xa hoi. hieu va cam ((tuc va) or (tuc xa)) danh ve ve triet*.
