Perhaps you should try some spelling variations:
ve triet » va trien, su triet
hanh lam » thanh lap, hanh kem, hanh va
hieu ve » hieu va, hieu van
su sach » so sach, vu sach
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
ve chat » va chat, van chat
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
lam ve » la ve, lam vu, nam 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 y ((nang xa) OR (nang ma)) hoi. hieu ve chat ((xuc va) or (tuc va)) hanh lam ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang xa) OR (nang ma)) hoi. hieu ve chat ((xuc va) OR (tuc va)) hanh lam ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang xa) OR (nang ma)) hoi. hieu ve chat ((xuc va) or (tuc va)) hanh lam ve triet".
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang xa) OR (nang ma)) hoi. hieu ve chat ((xuc va) or (tuc va)) hanh lam ve triet*.
