Perhaps you should try some spelling variations:
danh sai » dung sai, danh bat, danh dau
danh vai » danh va, doanh van, dang van
cam thuc » am thuc, nam thuc, cam thu
sach ty » sach y, sach tu, sach thu
te sach » toc sach
hang ca » hang va, nang cao, hang tai
hang xa » hoang xa, hang va, lang xa
cuu tre » cua tre, cau tren, cau treo
va cam » va cham, va cac, va cao

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 ((hang xa) OR (hang ca)) hoi. lieu va cam thuc vat ((danh vai) or (danh sai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((hang xa) OR (hang ca)) hoi. lieu va cam thuc vat ((danh vai) OR (danh sai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((hang xa) OR (hang ca)) hoi. lieu va cam thuc vat ((danh vai) or (danh sai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((hang xa) OR (hang ca)) hoi. lieu va cam thuc vat ((danh vai) or (danh sai)) cuu tre*.
