Perhaps you should try some spelling variations:
luoc van » luoc can, luc van, luot van
vu sach » vu bach, su sach, vu khach
hanh di » hanh vi, hanh de, hang di
luoc va » nuoc va, duoc va, loc va
va cham » va chat, va tham
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
cua tre » cua te, cuu tre, cua triet
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: vu sach y ((nang xa) OR (nang ma)) hoi. lieu va cham ((luoc van) OR (luoc va)) hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham ((luoc van) OR (luoc va)) hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham ((luoc van) OR (luoc va)) hanh di cua tre*.
