Perhaps you should try some spelling variations:
qua nhan » cua nhan, qua nhat, qua phan
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
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 hoa. hieu qua nhan luc va hanh ((doi cua) OR (dai cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoa. hieu qua nhan luc va hanh ((doi cua) or (dai cua)) tre*.
