Perhaps you should try some spelling variations:
qua nhan » cua nhan, qua nhat, qua phan
nhan luc » nang luc
hanh doi » thanh doi, hanh noi, hang doi
vu sach » vu bach, su sach, vu khach
va hanh » van hanh, va thanh, va danh
doi cua » dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, ma hoa, me hoi
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: vu sach y nang ((ma hoi) OR (xa hoi)). hieu qua nhan luc va hanh doi cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu sach y nang ((ma hoi) or (xa hoi)). hieu qua nhan luc va hanh doi cua tre*.
