Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
dung co » dung cho, dung cong, dung cua
va dung » van dung, va duong, vat dung
men lam » den lam, nen lam, tien lam
men dam » man dam, men da, mon dam
lang xa » lang ha, dang xay, lang van
dang xa » dang xay, dang ha, dang va
sac ky » cac ky, sai ky
co cua » con cua, ca cua, cong cua
so sac » so sach, so dac

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sac ky ((dang xa) OR (lang xa)) hoi. hieu ((men dam) or (men lam)) tu va dung co cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky ((dang xa) OR (lang xa)) hoi. hieu ((men dam) OR (men lam)) tu va dung co cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky ((dang xa) OR (lang xa)) hoi. hieu ((men dam) or (men lam)) tu va dung co cua tre*".
