Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
danh vi » hanh vi, dinh vi, danh di
hieu ve » hieu va, hieu van
te sach » toc sach
ba lang » ban lang, va lang, ba bang
xa lang » va lang, ha lang, xa bang
ve cham » va cham, ve chat, vu cham
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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: te sach ((xa lang) OR (ba lang)) xa hoi. hieu ve cham ((xuc va) OR (tuc xa)) danh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((xa lang) OR (ba lang)) xa hoi. hieu ve cham ((xuc va) or (tuc xa)) danh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ((xa lang) OR (ba lang)) xa hoi. hieu ve cham ((xuc va) or (tuc xa)) danh vi cua triet*.
