Perhaps you should try some spelling variations:
ve triet » va trien, su triet
chat xuc » chat huu, cam xuc, chao xu
va hanh » van hanh, va thanh, va danh
sach tu » sach thu, cach tu, sach ty
hieu ve » hieu va, hieu van
su sach » so sach, vu sach
nang xa » lang xa, nang ma, mang xa
ve chat » va chat, van chat
va dau » va dao
la ve » ly ve, ca ve, va ve

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

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