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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc va)) hanh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y 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 y 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 y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc va)) hanh lai cua tre*.
