Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh tai » thanh tai, hang tai, han tai
hanh lai » hanh lam, thanh lap, thanh loi
vu sach » vu bach, su sach, vu khach
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
ma hoi » mai hoi, ma hoa, me hoi
ve cam » ve cham, ve cac, va cam

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

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