Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
di cua » doi cua, de cua, do cua
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: te sac ky nang x hoi. hieu ve cam xuc ((va hanh) OR (va danh)) ((di cua) OR (dai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. hieu ve cam xuc ((va hanh) or (va danh)) ((di cua) OR (dai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. hieu ve cam xuc ((va hanh) or (va danh)) ((di cua) OR (dai cua)) tre*.
