Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
ban hanh » ban hang
so sach » so sanh, bo sach, co sach
vu cham » va cham, vu kham, tu cham
hieu vu » hieu va, hieu ve, hieu su
sach 2 » sach y
2 nang » v nang
x hoi » xa hoi, o hoi, x ho
va ve » va de, va le, va vo
va vi » ba vi

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: so sach 2 nang x hoi. hieu vu cham xuc ((van ban) OR (ban hanh)) ((va ve) OR (va vi)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach 2 nang x hoi. hieu vu cham xuc ((van ban) or (ban hanh)) ((va ve) OR (va vi)) triet~".
• Adding a wildcard symbol may retrieve word variants: so sach 2 nang x hoi. hieu vu cham xuc ((van ban) or (ban hanh)) ((va ve) OR (va vi)) triet*.
