Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
xa hanh » xa thanh, xa khanh, va hanh
sach ty » sach tu, sach thu, xach tay
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao
nang o » nang co, nang ho, nang ro
ve cam » ve cham, ve cac, ve cai
o hoi » co hoi, o hoc, o hai

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) OR (sach y)) nang o hoi. hieu ((ve cam) OR (va cam)) tuc xa hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) nang o hoi. hieu ((ve cam) or (va cam)) tuc xa hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) nang o hoi. hieu ((ve cam) or (va cam)) tuc xa hanh vai cua tre*.
