Perhaps you should try some spelling variations:
dang xay » dang van, van xay
tu sach » thu sach, su sach, te sach
ve pham » vi pham, v pham, ve phat
hanh hu » hanh khu, hanh nhu, hanh tu
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
ve phan » va phan, ke phan, ve phat
sach ty » sach y, sach tu, sach thu
lang xa » lang ha, lang van
hu cua » tu cua, vu cua
cua tu » cua tuc, cua su, cua cu

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: tu sach ty ((lang xa) OR (dang xay)) hoi. hieu ((ve pham) OR (ve phan)) thuc va hanh hu cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((lang xa) OR (dang xay)) hoi. hieu ((ve pham) or (ve phan)) thuc va hanh hu cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((lang xa) OR (dang xay)) hoi. hieu ((ve pham) or (ve phan)) thuc va hanh hu cua tu*.
