Perhaps you should try some spelling variations:
thu sach » tu sach, thuat sach, thuoc sach
hieu van » hieu va, thien van, lieu va
cau xuc » cam xuc, cau truc, chat xuc
sach ky » sac ky, sach y, sach ty
cau luc » cau truc, cau phuc
va hanh » van hanh, va thanh, va danh
x hoi » xa hoi, o hoi, x ho
vi va » vi van, vai va, bi va
vu va » vu van, tu va, su va

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