Perhaps you should try some spelling variations:
dinh thi » dinh tri
bac viet » hoc viet, mai viet, dao viet
sang ky » sang kyo, dang ky, tang ky
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
va dinh » van dinh, va kinh, va tinh
thi bac » thi bach, thi ba, thi tac
san ky » dan ky, ban ky, tan ky
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va

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

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