Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
ban hang » ngan hang
su sach » so sach, vu sach
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh

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 chuc)) ((ban hanh) OR (ban hang)) vai cuu 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 chuc)) ((ban hanh) OR (ban hang)) vai cuu 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 chuc)) ((ban hanh) OR (ban hang)) vai cuu tre*".
