Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
va tham » van tham, va thanh, va thuat
va cham » va chat
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
te cac » tu cac, ve cac, te cao
loc va » hoc 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: te cac ky nang xa hoi. hieu ((va tham) OR (va cham)) loc va hanh vi ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang xa hoi. hieu ((va tham) OR (va cham)) loc va hanh vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang xa hoi. hieu ((va tham) OR (va cham)) loc va hanh vi ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang xa hoi. hieu ((va tham) OR (va cham)) loc va hanh vi ((cua tre) or (cuu tre))*.
