Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
xa thanh » va thanh, ha thanh, ta thanh
hieu van » hieu va, thien van, lieu va
vu sach » su sach, vu khach
cac tuc » cac toc, cac tu, cac tac
van cac » van hac, van cau, van bac
ty hang » ly hang, ty xang, thi hang
ty lang » tay lang, ty xang, tu lang
vi cua » vai cua, di cua
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ((ty lang) OR (ty hang)) xa hoi. hieu van cac tuc xa thanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) ((ty lang) or (ty hang)) xa hoi. hieu van cac tuc xa thanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (vu bach)) ((ty lang) or (ty hang)) xa hoi. hieu van cac tuc xa thanh vi cua te*.
