Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
tang van » dang van, hoang van, trong van
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
van cam » van lam, van cau, van dam
te sach » toc sach
sach ky » sac ky, sach y, sach ty
lang xa » lang ha, dang xay, lang van
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.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((lang xa) or (tang van)) hoi. hieu ((van cam) OR (van nam)) xuc va hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang xa) OR (tang van)) hoi. hieu ((van cam) OR (van nam)) xuc va hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang xa) or (tang van)) hoi. hieu ((van cam) OR (van nam)) xuc va hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang xa) or (tang van)) hoi. hieu ((van cam) OR (van nam)) xuc va hanh vai cua tre*.
