Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
nang lai » nang tai, mang lai, nang cai
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
lai hoa » dai hoa, loai hoc
sac ky » sai ky
xuc va » duc va, tuc va, luc va
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: su ((sac ky) OR (cac ky)) nang lai hoa. hieu ve cac xuc va hanh vai ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) nang lai hoa. hieu ve cac xuc va hanh vai ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) OR (cac ky)) nang lai hoa. hieu ve cac xuc va hanh vai ((cua triet) or (va triet))".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) OR (cac ky)) nang lai hoa. hieu ve cac xuc va hanh vai ((cua triet) or (va triet))*.
