Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
van cham » van chat, van tham, va cham
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hanh di » hanh vi, hanh de, hang di
y nang » ky nang, ly nang, v nang
soc va » loc va, doc va, goc va
di cua » dai cua, doi cua, de cua

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 y nang xa hoi. thien van cham ((soc va) OR (hoc va)) hanh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. thien van cham ((soc va) or (hoc va)) hanh di cua triet*.
