Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
van chat » cao chat
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
sach ky » sac ky, sach y, sach kem
sach ty » sach y, sach tu, sach thu
van cau » van dau, van hau, toan cau
tuc va » thuc va, truc va, tuc xa
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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 ky) or (sach ty)) nang x hoi. hieu ((van cau) OR (van chat)) tuc va hanh di cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) nang x hoi. hieu ((van cau) OR (van chat)) tuc va hanh di cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach ty)) nang x hoi. hieu ((van cau) OR (van chat)) tuc va hanh di cua viet*".
