Perhaps you should try some spelling variations:
sang tao » hang tai
te sach » toc sach
va danh » va dinh, va dan, va hanh
ky sang » ky nang, ky dang, ky tang
tao hoi » tao khoi, tao boi, tay hoi
hieu va » hieu qua
sach ky » sac ky, sach y, sach ty
cam luc » cam xuc, cau luc
vi cua » vai cua
luc va » duc va, tuc va, loc va
di cua » dai cua, doi cua, de 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: te sach ky sang tao hoi. ((hieu va) OR (lieu va)) cam luc va danh ((vi cua) OR (di cua)) vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang tao hoi. ((hieu va) or (lieu va)) cam luc va danh ((vi cua) OR (di cua)) vat~".
• Adding a wildcard symbol may retrieve word variants: te sach ky sang tao hoi. ((hieu va) or (lieu va)) cam luc va danh ((vi cua) OR (di cua)) vat*.
