Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, pham duc
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
vi cau » ve cau, di cau, viet cau
va cau » van cau, va cac, va dau
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 ky nang x hoi. hieu van ((cham xuc) OR (cham soc)) va hanh ((vi cau) OR (va cau)) tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. hieu van ((cham xuc) or (cham soc)) va hanh ((vi cau) OR (va cau)) tren~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x hoi. hieu van ((cham xuc) or (cham soc)) va hanh ((vi cau) OR (va cau)) tren*.
