Perhaps you should try some spelling variations:
doanh vang » doanh sang, doanh quang, doan van
doanh van » doan van, doanh va, doanh ban
nhan luc » nang luc
cham luc » cham soc, cham cuu, chat lua
te sach » toc sach
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v 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 y nang xa hoi. hieu ve ((cham luc) OR (nhan luc)) va ((doanh vang) OR (doanh van)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ve ((cham luc) or (nhan luc)) va ((doanh vang) OR (doanh van)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ve ((cham luc) or (nhan luc)) va ((doanh vang) OR (doanh van)) cua tre*.
