Perhaps you should try some spelling variations:
van cham » van chat, van tham, va cham
hieu van » hieu va, thien van, lieu va
cham tuc » nham thuc, pham thuc, tham thuc
hoi cua » hoi chuc
hai cua » thai cua, dai cua, lai cua
va hanh » van hanh, va thanh, va danh
te sach » toc sach
va nang » van nang, da nang, cam nang
tuc va » thuc va, truc va, tuc xa
v nang » vu nang, van nang, voi nang

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 ((v nang) OR (va nang)) xa hoi. hieu van cham tuc va hanh ((hai cua) OR (hoi cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) OR (va nang)) xa hoi. hieu van cham tuc va hanh ((hai cua) or (hoi cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) OR (va nang)) xa hoi. hieu van cham tuc va hanh ((hai cua) or (hoi cua)) tre*.
