Perhaps you should try some spelling variations:
hanh va » hang va, hanh vi
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
van cau » van dau, van hau, van chat
van cam » van nam, van lam, van dam
te sach » toc sach
sach ty » sach y, sach tu, sach thu
dang ha » dong ha, dung ha, lang ha
dang xa » dang xay, lang xa, dang va
cua tre » cua te, cuu tre, cua triet
va cua » va chua, via cua, ca 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: te sach ty ((dang xa) OR (dang ha)) hoi. thien ((van cam) OR (van cau)) thuc va hanh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((dang xa) OR (dang ha)) hoi. thien ((van cam) or (van cau)) thuc va hanh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((dang xa) OR (dang ha)) hoi. thien ((van cam) or (van cau)) thuc va hanh va cua tre*.
