Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
hanh vai » hanh vi, hanh va, hanh tai
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
sach ky » sach y, sach ty, sach kem
hieu ve » hieu va, hieu van
sac ky » cac ky, sai ky
x hoi » xa hoi, o hoi, x ho
ve am » va am

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 (sac ky)) nang x hoi. hieu ve am thuc va hanh vai ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang x hoi. hieu ve am thuc va hanh vai ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) nang x hoi. hieu ve am thuc va hanh vai ((cua triet) or (va triet))*".
