Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van tham » van thanh, van tuan, van chat
tu sach » thu sach, su sach, te sach
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((nang xa) OR (lang xa)) hoi. hieu van tham ((xuc va) or (tuc xa)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (lang xa)) hoi. hieu van tham ((xuc va) OR (tuc xa)) hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) OR (lang xa)) hoi. hieu van tham ((xuc va) or (tuc xa)) hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang xa) OR (lang xa)) hoi. hieu van tham ((xuc va) or (tuc xa)) hanh vi cua te*.
