Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
qua cham » qua hai, qua cac, va cham
van hanh » van thanh, ban hanh, van anh
va triet » va thiet, va trien, ve triet
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
va hanh » va thanh, va danh, ban hanh
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: su sach ky nang x hoi. hieu qua cham soc ((va hanh) or (van hanh)) vi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu qua cham soc ((va hanh) OR (van hanh)) vi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu qua cham soc ((va hanh) or (van hanh)) vi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x hoi. hieu qua cham soc ((va hanh) or (van hanh)) vi ((cua triet) OR (va triet))*.
