Perhaps you should try some spelling variations:
cham tuc » nham thuc, pham thuc, tham thuc
cua viet » ca viet, cua vat, cua dieu
hanh moi » thanh moi, hanh noi, hanh mot
lang van » dang van, tang van, hoang van
tu sach » thu sach, su sach, te sach
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
mang xa » lang xa, mang may, dang xay
tuc va » thuc va, truc va, tuc xa

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((mang xa) or (lang van)) hoi. hieu ve cham tuc va hanh moi ((cua viet) OR (hoa viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((mang xa) OR (lang van)) hoi. hieu ve cham tuc va hanh moi ((cua viet) OR (hoa viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((mang xa) or (lang van)) hoi. hieu ve cham tuc va hanh moi ((cua viet) OR (hoa viet))*".
