Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
dinh ve » dinh ket, dinh van
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
tai ky » thai ky, trai ky, sai ky
va nam » van nam, ha nam, va nay
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 tai ky nang xa hoi. hieu va nam ((xuc va) OR (duc va)) dinh ve ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te tai ky nang xa hoi. hieu va nam ((xuc va) OR (duc va)) dinh ve ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te tai ky nang xa hoi. hieu va nam ((xuc va) OR (duc va)) dinh ve ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te tai ky nang xa hoi. hieu va nam ((xuc va) OR (duc va)) dinh ve ((cua tre) or (cuu tre))*.
