Perhaps you should try some spelling variations:
thi hanh » thi thanh
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
lang xa » lang ha, dang xay, lang van
thi van » thi lan, thi nang
vai cua » dai cua, hai cua, lai cua
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: te sach y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc vat)) hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) OR (thuc vat)) hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc vat)) hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. ((thi van) OR (thi hanh)) cam ((xuc va) or (thuc vat)) hanh vai cua tre*.
