Perhaps you should try some spelling variations:
thi hanh » thi thanh
hanh lai » hanh lam, hanh tai, thanh lap
lai cua » dai cua, hai cua, lai chau
thuc va » thuc vat, thuc dan, thuc day
sach ty » sach y, sach tu, sach thu
tu sach » thu sach, su sach, te sach
thi van » thi lan, thi nang
lang xa » lang ha, dang xay, lang van
ty lang » tay lang, ty xang, ty hang
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va

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. ((thi van) OR (thi hanh)) cam ((xuc va) OR (thuc va)) hanh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc va)) hanh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc va)) hanh lai cua tre*.
