Perhaps you should try some spelling variations:
van chat » cao chat
chat xuc » chat huu, cam xuc, chao xu
va triet » va trien, ve triet, cua triet
hanh lam » thanh lap, hanh kem, hanh va
ban hanh » ban hang
hieu van » hieu va, thien van, lieu va
xuc ban » duc ban, cuc ban, quoc ban
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
nang xa » lang xa, nang ma, mang xa
thiet » thieu

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ((nang xa) OR (nang x)) hoi. hieu van chat xuc ban hanh lam ((va triet) or (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((nang xa) OR (nang x)) hoi. hieu van chat xuc ban hanh lam ((va triet) OR (va thiet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang xa) OR (nang x)) hoi. hieu van chat xuc ban hanh lam ((va triet) or (va thiet))*".
