Perhaps you should try some spelling variations:
xach tay » canh tay
nam thuc » nam thuoc, am thuc, nam thu
vat dung » van dung, viet dung, mat duong
nang xa » nang x, lang xa, nang ma
qua nam » quan nam, cua nam, quang nam
va dung » van dung, va duong, va ung
doi cuu » doi cua, doi cuoc
cuu tre » cua tre, cau tren, cau treo

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((xach tay) or (sach y)) nang xa hoi. hieu qua nam thuc ((vat dung) OR (va dung)) doi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((xach tay) OR (sach y)) nang xa hoi. hieu qua nam thuc ((vat dung) OR (va dung)) doi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((xach tay) or (sach y)) nang xa hoi. hieu qua nam thuc ((vat dung) OR (va dung)) doi cuu tre*".
