Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
ve triet » va trien, su triet
thanh vi » hanh vi, thanh va, thanh ve
xuc ban » duc ban, cuc ban, quoc ban
sach ty » sach y, sach tu, sach thu
vu sach » vu bach, su sach, vu khach
sang ma » tang ma, nang ma, sang tao
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cai
vi ve » va ve, gi ve, ve ve

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 ty ((nang xa) OR (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh vi ve triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((nang xa) or (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh vi ve triet~".
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((nang xa) or (sang ma)) hoi. hieu ((ve cam) OR (ve cac)) xuc ban thanh vi ve triet*.
