Perhaps you should try some spelling variations:
cham luoc » cham soc, khai luoc, kham cuoc
thanh dai » thanh hai, thanh tai, thanh dat
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
vu sach » vu bach, su sach, vu khach
nang ma » tang ma, sang ma, nang cao
va cham » va chat, va tham
luoc va » nuoc va, duoc va, loc va
cua tre » cua te, cuu tre, dua tren

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 x) OR (nang ma)) hoi. lieu va cham luoc va thanh dai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y ((nang x) or (nang ma)) hoi. lieu va cham luoc va thanh dai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: vu sach y ((nang x) or (nang ma)) hoi. lieu va cham luoc va thanh dai ((cua tre) OR (cua triet))*.
