Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cham tuc » nham thuc, pham thuc, tham thuc
hanh va » hang va, hanh vi
danh va » doanh va, anh va, dan va
hieu va » lieu va, hieu qua
va cham » va chat, va tham
lang xa » lang ha, dang xay, lang van
su sach » so sach, vu sach
o lang » hoa lang, hoi lang
tuc va » thuc va, truc va, tuc xa
su sac » su cac, su xac

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) or (su sach)) o lang xa hoi. hieu va cham tuc va ((danh va) OR (hanh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) o lang xa hoi. hieu va cham tuc va ((danh va) OR (hanh va)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su sach)) o lang xa hoi. hieu va cham tuc va ((danh va) OR (hanh va)) cua triet*".
