Perhaps you should try some spelling variations:

cham tuc » nham thuc, pham thuc, tham thuc
cua tre » cua te, cuu tre, cua triet
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
va cham » va chat, va tham
hieu va » lieu va, hieu qua
lang xa » lang ha, lang van
ca cua » co cua
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac o ((lang xa) or (dang xay)) hoi. hieu va cham tuc ((va danh) OR (va hanh)) ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac o ((lang xa) OR (dang xay)) hoi. hieu va cham tuc ((va danh) OR (va hanh)) ca cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac o ((lang xa) or (dang xay)) hoi. hieu va cham tuc ((va danh) OR (va hanh)) ca cua tre*".
