Perhaps you should try some spelling variations:

tham nang » nham nang, tham lang, tham nhung
pham chuc » pham duc, pham huu, kham chua
so sach » so sanh, bo sach, co 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
cua tu » cua tuc, cua su, cua cu

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