Perhaps you should try some spelling variations:
danh tai » doanh tai, dinh tai, hanh tai
te sach » toc sach
tai cua » thai cua, tai cuc, tri cua
thuc va » thuc vat, thuc dan, thuc day
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cuu tre, cua triet
lang ha » long ha
lang xa » dang xay, lang van
tuc va » truc va, tuc xa, duc va
va cao » va cac, va co, 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 ky ((lang xa) OR (lang ha)) hoi. lieu va cao ((tuc va) or (thuc va)) danh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang xa) OR (lang ha)) hoi. lieu va cao ((tuc va) OR (thuc va)) danh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang xa) OR (lang ha)) hoi. lieu va cao ((tuc va) or (thuc va)) danh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang xa) OR (lang ha)) hoi. lieu va cao ((tuc va) or (thuc va)) danh tai cua tre*.
