Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao
loc va » hoc va, luc va
di cua » dai cua, doi cua, de cua

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 y ((nang xa) OR (nang x)) hoi. hieu ((ve cam) OR (va cam)) loc va hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang xa) or (nang x)) hoi. hieu ((ve cam) or (va cam)) loc va hanh di cua tre*.
