Perhaps you should try some spelling variations:
dinh tai » dinh toai, dinh tri, dinh thi
su sach » so sach
tai cua » thai cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
vu sach » vu bach, vu khach
tuc va » thuc va, truc va, duc va
y lang » o lang, _ lang, tay lang
ve cam » ve cham, ve cac, va cam

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) OR (vu sach)) y lang xa hoi. hieu ve cam ((tuc va) or (tuc xa)) dinh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y lang xa hoi. hieu ve cam ((tuc va) OR (tuc xa)) dinh tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y lang xa hoi. hieu ve cam ((tuc va) or (tuc xa)) dinh tai cua tre*".
