Perhaps you should try some spelling variations:
chang xu » chang xue, chao xu, thong xu
hieu van » hieu va, thien van, lieu va
tu sach » thu sach, su sach, te sach
sach ly » sach y, sach lo, sach ty
van cam » van nam, van lam, van cau
luc van » luoc van, luu van, duc van
cuu tre » cua tre, cau tren, cau treo
hang x » nang x, hoang xa, hang nxb
vi cuu » vi luu, vinh cuu

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 ly ((hang x) OR (chang xu)) hoi. hieu van cam ((luc van) or (duc va)) hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((hang x) OR (chang xu)) hoi. hieu van cam ((luc van) OR (duc va)) hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((hang x) OR (chang xu)) hoi. hieu van cam ((luc van) or (duc va)) hanh vi cuu tre*".
