Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh lai » hanh lam, hanh tai, thanh lap
va hanh » van hanh, va thanh, va danh
te sach » toc sach
tu nong » tu dong, tu cong, tu tong
tu nang » tru nang, tu nano, tu lang
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
cua te » cua tu

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 ((tu nang) OR (tu nong)) xa hoi. hieu ve cam xuc va hanh lai ((cua te) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tu nong)) xa hoi. hieu ve cam xuc va hanh lai ((cua te) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) OR (tu nong)) xa hoi. hieu ve cam xuc va hanh lai ((cua te) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu nang) OR (tu nong)) xa hoi. hieu ve cam xuc va hanh lai ((cua te) or (cua triet))*.
