Perhaps you should try some spelling variations:
pham cuc » pham chuc, pham duc, pham cua
ban hanh » ban hang
sach ky » sac ky, sach y, sach ty
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
va cuu » va cau, va chu
va huu » vu huu

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 ky dang xa hoi. hieu ve ((cam xuc) or (pham cuc)) ban hanh ((va cuu) OR (va huu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xa hoi. hieu ve ((cam xuc) OR (pham cuc)) ban hanh ((va cuu) OR (va huu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xa hoi. hieu ve ((cam xuc) or (pham cuc)) ban hanh ((va cuu) OR (va huu)) tre*".
