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
van hanh » van thanh, ban hanh, van anh
su sach » so sach, vu sach
ky dang » ky nang, ky danh
va hanh » va thanh, va danh, ban hanh
y dang » 2 dang, _ dang, b dang
vi cua » vai cua, di cua

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