Perhaps you should try some spelling variations:

dinh thi » dinh tri
thu bang » thu ban, thu hang, chu bang
hieu van » hieu va, thien van, lieu va
va danh » va dan, va hanh, dia danh
va dinh » van dinh, va kinh, va tinh
tu sach » thu sach, su sach, te sach
lam xuc » cam xuc, lam duoc
van lam » van nam

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((thu nang) OR (thu bang)) xa hoi. hieu van lam xuc ((va danh) or (va dinh)) dinh thi treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thu nang) OR (thu bang)) xa hoi. hieu van lam xuc ((va danh) OR (va dinh)) dinh thi treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thu nang) OR (thu bang)) xa hoi. hieu van lam xuc ((va danh) or (va dinh)) dinh thi treo*".
