Perhaps you should try some spelling variations:
lang dai » lang hai, lang mai, lang chai
so triet » su triet, so thiet, bo triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
xuc va » tuc va, luc va, xac va

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 cac ((xuc va) OR (duc va)) lang dai so triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ve cac ((xuc va) OR (duc va)) lang dai so triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ve cac ((xuc va) OR (duc va)) lang dai so triet*.
