Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
va cham » va chat, va tham
tu sach » thu sach, te sach, tu cach
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
ve cham » ve chat, 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 (su sach)) y nang xa hoi. hieu ((ve cham) OR (va cham)) soc va thanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) y nang xa hoi. hieu ((ve cham) OR (va cham)) soc va thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) y nang xa hoi. hieu ((ve cham) OR (va cham)) soc va thanh vi cua triet*.
