Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ve triet » va trien, su triet
van hanh » van thanh, ban hanh, van anh
soc van » hoc van, oc van, sac van
hanh di » hanh vi, hanh de, hang di
su sach » so sach, vu sach
sach yu » sach y, sach tu, sach uu
hieu va » hieu qua
hang xa » hoang xa, hang va, hang ca
yu hang » yu zhang, yu pang, yu wang

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: su sach yu hang xa hoi. ((hieu va) OR (lieu va)) cham soc van hanh di ((cua triet) OR (ve triet))~.
• Adding a wildcard symbol may retrieve word variants: su sach yu hang xa hoi. ((hieu va) or (lieu va)) cham soc van hanh di ((cua triet) or (ve triet))*.
