Perhaps you should try some spelling variations:
ban manh » van manh, ban mach, ban anh
ban hanh » ban hang
ve triet » va trien, su triet
te sach » toc sach
hieu ve » hieu van
hieu va » lieu va, hieu qua
van xa » van xay, van ha, dan xa
hai ve » hoai ve, hai va, hai vu
y van » ly van, ty van, _ van

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