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

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