Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
lang van » dang van, tang van, hoang van
vai cuu » vai cua
nam xuc » cam xuc, nam xua, nam thuc
sach ty » sach y, sach tu, sach thu
te sach » toc sach
lang xa » lang ha, dang xay
cuu tre » cua tre, cau tren, cau treo
va dan » ca dan, va dao, va dap
va dau » va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((lang xa) or (lang van)) hoi. hieu van nam xuc ((va dan) OR (va dau)) vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((lang xa) OR (lang van)) hoi. hieu van nam xuc ((va dan) OR (va dau)) vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((lang xa) or (lang van)) hoi. hieu van nam xuc ((va dan) OR (va dau)) vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((lang xa) or (lang van)) hoi. hieu van nam xuc ((va dan) OR (va dau)) vai cuu tre*.
