Perhaps you should try some spelling variations:
vuc nang » cuc nang, vu nang, chuc nang
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
xuc van » duc van, luc van, vuc van
hoi cua » hoi chuc
doi cua » dai cua
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
v nang » va nang, vu nang, van 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 (vuc nang)) xa hoi. hieu ve cam xuc van hanh ((doi cua) OR (hoi cua)) tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) or (vuc nang)) xa hoi. hieu ve cam xuc van hanh ((doi cua) OR (hoi cua)) tuc~".
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) or (vuc nang)) xa hoi. hieu ve cam xuc van hanh ((doi cua) OR (hoi cua)) tuc*.
