Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
tinh hoa » trinh hoa, tinh hoc, minh hoa
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cao duc » dao duc, cao suc, giao duc
va tinh » may tinh
te sac » te sach, te cac, te san
ve cac » va cac, vien cac
ve cao » va cao, ve bao, ve co

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (ve cac)) ky nang xa hoi. hieu ve cao duc va tinh hoa ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (ve cac)) ky nang xa hoi. hieu ve cao duc va tinh hoa ((cua triet) OR (su triet))~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (ve cac)) ky nang xa hoi. hieu ve cao duc va tinh hoa ((cua triet) OR (su triet))*.
