Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc day » thuc dan, thuc vat
day danh » day manh, dai danh, dao danh
danh dai » danh dau, danh di, danh sai
hieu va » lieu va, hieu qua
te sac » te sach, te cac, te san
ve cac » va cac, vien cac
x hoi » o hoi, x ho, 5 hoi
va am » va lam, va cam

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 ((x hoi) OR (xa hoi)). hieu va am thuc day danh dai cua triet~.
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (ve cac)) ky nang ((x hoi) or (xa hoi)). hieu va am thuc day danh dai cua triet*.
