Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
dan tinh » doan tinh, dang tinh, dan trinh
tinh thi » trinh thi, tinh thai, dinh thi
su sach » so sach, vu sach
lang xa » lang ha, dang xay, lang van
ve cham » va cham, ve chat, vu cham
thi cua » thai cua, thi cuc, tri cua
y lang » o lang, _ lang, tay lang
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)) thuc dan tinh thi cua te~.
• Adding a wildcard symbol may retrieve word variants: su sach y lang xa hoi. hieu ((ve cam) or (ve cham)) thuc dan tinh thi cua te*.
