Perhaps you should try some spelling variations:
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
thanh vi » hanh vi, thanh va, thanh ve
xuc gia » duc gia, luc gia, tuc gia
hieu ve » hieu va, hieu van
tang ma » mang may, tang van
nang ma » sang ma, nang cao, mang may
sai ky » sac ky
ve cam » ve cham, ve cac, va cam
su sai » su tai, su hai, su dai

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

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