Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
qua nhan » cua nhan, qua nhat, qua phan
nhan luc » nang luc
va thanh » gia thanh, ban thanh, va tinh
su sach » so sach, vu sach
nang ma » tang ma, sang ma, nang cao
va hanh » van hanh, va danh, ban hanh
cua tre » cua te, cuu tre, dua tren
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa

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 qua nhan luc ((va hanh) OR (va thanh)) dai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. hieu qua nhan luc ((va hanh) or (va thanh)) dai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoi. hieu qua nhan luc ((va hanh) or (va thanh)) dai ((cua tre) OR (cua triet))*.
