Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
viet cua » viec cua, viet qua, biet cua
tu sach » thu sach, te sach, tu cach
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc ban » duc ban, cuc ban, quoc ban
ban anh » ban hanh, ban banh, ban danh
viet ca » viet ha, viet co, viet a
x hoi » xa hoi, o hoi, x ho

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)) ky nang x hoi. hieu ve cham xuc ban anh ((viet cua) OR (viet ca)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky nang x hoi. hieu ve cham xuc ban anh ((viet cua) OR (viet ca)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ky nang x hoi. hieu ve cham xuc ban anh ((viet cua) OR (viet ca)) tre*.
