Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
tham nang » nham nang, tham lang, tham nhung
so sach » bo sach, co sach, hoc sach
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
ve pham » vi pham, v pham, ve phan
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
so sanh » do sanh
chau te » chau tho

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) OR (so sanh)) tham nang xa hoi. hieu ve pham chuc ((va hanh) or (va danh)) lai chau te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) tham nang xa hoi. hieu ve pham chuc ((va hanh) OR (va danh)) lai chau te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) tham nang xa hoi. hieu ve pham chuc ((va hanh) or (va danh)) lai chau te".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (so sanh)) tham nang xa hoi. hieu ve pham chuc ((va hanh) or (va danh)) lai chau te*.
