Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va hanh » van hanh, va thanh, va danh
ve chat » va chat, van chat
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
vu sach » vu bach, su sach, vu khach
ve cham » va cham, vu cham, ve chim
y nang » ky nang, ly nang, v nang
soc va » hoc va, loc va, doc va
vi cua » vai cua, di 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: ((tu sach) OR (vu sach)) y nang xa hoi. hieu ((ve cham) OR (ve chat)) soc va hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) y nang xa hoi. hieu ((ve cham) OR (ve chat)) soc va hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu sach)) y nang xa hoi. hieu ((ve cham) OR (ve chat)) soc va hanh vi cua triet*.
