Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
cham tuc » nham thuc, pham thuc, tham thuc
va hanh » van hanh, va danh, ban hanh
sach ky » sac ky, sach y, sach ty
vu sach » vu bach, su sach, vu khach
hieu vu » hieu va, hieu ve, hieu su
lang xa » lang ha, dang xay, lang van
tang xa » trang xa, tang ma, tang ha
vu cham » va cham, vu kham, tu cham

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky ((tang xa) OR (lang xa)) hoi. hieu vu cham tuc ((va hanh) or (va thanh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky ((tang xa) OR (lang xa)) hoi. hieu vu cham tuc ((va hanh) OR (va thanh)) dai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky ((tang xa) OR (lang xa)) hoi. hieu vu cham tuc ((va hanh) or (va thanh)) dai cua triet*".
