Perhaps you should try some spelling variations:
van trieu » tan trieu, van tieu, van hieu
hieu van » hieu va, thien van, lieu va
te sach » toc sach
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
duc ban » duc van, duc man, duc manh
dua ban » dia ban, cua ban, qua ban
y nang » ky nang, ly nang, v nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang xa hoi. hieu van cam ((((duc ban) or (duc tan))) or (dua ban)) hanh vi van trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu van cam ((((duc ban) OR (duc tan))) OR (dua ban)) hanh vi van trieu.
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu van cam ((((duc ban) or (duc tan))) or (dua ban)) hanh vi van trieu*.
