Perhaps you should try some spelling variations:
cham luoc » cham soc, khai luoc, kham cuoc
luoc van » luoc can, luoc va, luc van
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
va cham » va chat, va tham
vu sach » vu bach, su sach, vu khach
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
cua tre » cua te, cuu tre, cua triet

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 ((hanh di) OR (hanh de)) 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 ((hanh di) OR (hanh de)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach y ((nang xa) or (nang ma)) hoi. lieu va cham luoc van ((hanh di) OR (hanh de)) cua tre*.
