Perhaps you should try some spelling variations:
mai khoi » mai khoa, tai khoa, cac khoi
van hanh » van thanh, ban hanh, van anh
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, vuc van
hieu ve » hieu va, hieu van
te sach » toc sach
ly nang » ky nang, ly hang, ly vang
y nang » ky nang, v nang, may nang
ve cam » ve cham, ve cac, va cam
di cua » dai cua, doi cua, de cua
cua te » cua tu

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 ((y nang) OR (ly nang)) ((xa hoi) OR (mai khoi)). hieu ve cam xuc van hanh di cua te~.
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (ly nang)) ((xa hoi) or (mai khoi)). hieu ve cam xuc van hanh di cua te*.
