Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
te sac » te sach, te cac, te san
tu ban » thu ban, te ban
cam tu » cam thu, nam tu, dam tu
sac ky » cac ky, sai ky

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 nang xa hoi. ((hieu ve) OR (hieu va)) cam tu ban ((thanh toan) or (tinh toan)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu ban ((thanh toan) OR (tinh toan)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu ban ((thanh toan) or (tinh toan)) su triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu ban ((thanh toan) or (tinh toan)) su triet*.
