Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
vu sach » vu bach, su sach, vu khach
sach ty » sach y, sach tu, sach thu
nang xa » lang xa, nang ma, mang xa
van cam » van nam, van lam, van cau
dinh tu » danh tu, dinh cu, tinh tu
xuc va » tuc va, luc va, xac va
tu cua » hu cua, vu 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 ty ((nang xa) OR (nang x)) hoi. hieu van cam ((xuc va) OR (duc va)) dinh tu cua te~.
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((nang xa) or (nang x)) hoi. hieu van cam ((xuc va) or (duc va)) dinh tu cua te*.
