Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
sinh y » sinh ly
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sinh y nang xa hoi. ((hieu ve) or (lieu va)) cam xuc va hanh vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh y nang xa hoi. ((hieu ve) OR (lieu va)) cam xuc va hanh vi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh y nang xa hoi. ((hieu ve) or (lieu va)) cam xuc va hanh vi ((cua tre) OR (cuu tre))*".
