Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
duy sang » duy van, duy can, duy anh
hanh vai » hanh va, hanh tai, hanh van
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
ma hoi » mai hoi, xa hoi, ma hoa
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((duy sang) or (ky nang)) ma hoi. hieu ve cam xuc va ((hanh vai) OR (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((duy sang) OR (ky nang)) ma hoi. hieu ve cam xuc va ((hanh vai) OR (hanh vi)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((duy sang) or (ky nang)) ma hoi. hieu ve cam xuc va ((hanh vai) OR (hanh vi)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((duy sang) or (ky nang)) ma hoi. hieu ve cam xuc va ((hanh vai) OR (hanh vi)) cua triet*.
