Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
ban hanh » ban hang
hanh tai » thanh tai, hang tai, han tai
nang co » nang cao, nang doc, nang noi
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
xuc ban » duc ban, cuc ban, quoc ban
sac ky » sai ky
co loi » co hoi
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sac ky) or (cac ky)) nang co loi. hieu ve cac xuc ban hanh tai ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (cac ky)) nang co loi. hieu ve cac xuc ban hanh tai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) or (cac ky)) nang co loi. hieu ve cac xuc ban hanh tai ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) or (cac ky)) nang co loi. hieu ve cac xuc ban hanh tai ((cua triet) OR (cua viet))*.
