Perhaps you should try some spelling variations:
thien van » thi van
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
tinh cuu » trinh cuu, dinh cuu, tinh cua
van hanh » van thanh, ban hanh, van anh
hieu van » hieu va, lieu va, hieu ve
tu sach » thu sach, su sach, te sach
xuc van » duc van, luc van, vuc van
lam xuc » cam xuc, lam duoc
nang ma » tang ma, nang cao, mang may
sang ma » tang ma, sang tao, mang may
cuu tre » cua tre, cau tren, cau treo

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: tu sach y ((sang ma) OR (nang ma)) hoi. ((hieu van) OR (thien van)) lam xuc van hanh tinh cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((sang ma) or (nang ma)) hoi. ((hieu van) OR (thien van)) lam xuc van hanh tinh cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((sang ma) or (nang ma)) hoi. ((hieu van) OR (thien van)) lam xuc van hanh tinh cuu tre*.
