Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
vi cua » vai cua, di cua
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
su sac » su sach, su cac
su xac » pu xac, su cac
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) OR (su xac)) ky nang xa hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang xa hoi. hieu ve cac ((xuc va) OR (luc va)) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky nang xa hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky nang xa hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet*.
