Perhaps you should try some spelling variations:
hieu cua » hieu qua, dieu cua, bieu cua
cua nhan » ca nhan, cua ngan, cua nha
nhan luc » nang luc
su sach » so sach, vu sach
nang ma » tang ma, sang ma, nang cao
va hanh » van hanh, va thanh, va danh
doi cua » hoi cua
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
luc va » duc va, tuc va, loc va

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: su sach y nang ma hoi. hieu cua nhan luc va hanh ((doi cua) OR (dai cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoi. hieu cua nhan luc va hanh ((doi cua) or (dai cua)) tre*.
