Perhaps you should try some spelling variations:
dinh thi » dinh tri
ve cham » va cham, ve chat, vu cham
thi cua » thai cua, thi cuc, tri cua
truc va » thuc va, thuc vat, trung va
su sach » so sach, vu sach
lang xa » lang ha, dang xay, lang van
y lang » o lang, _ lang, tay lang
tuc va » thuc va, tuc xa, duc va
ve cam » ve cac, va cam, ve cai
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. hieu ((ve cam) OR (ve cham)) ((tuc va) OR (truc va)) dinh thi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y lang xa hoi. hieu ((ve cam) or (ve cham)) ((tuc va) OR (truc va)) dinh thi cua te~".
• Adding a wildcard symbol may retrieve word variants: su sach y lang xa hoi. hieu ((ve cam) or (ve cham)) ((tuc va) OR (truc va)) dinh thi cua te*.
