Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hang doi » hang di, hang loi, huong doi
hanh doi » thanh doi, hanh noi, hanh moi
vu sach » vu bach, su sach, vu khach
nang ma » tang ma, sang ma, nang cao
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: vu sach y nang ma hoi. hieu qua ((nhan luc) OR (nang luc)) va ((hanh doi) OR (hang doi)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang ma hoi. hieu qua ((nhan luc) or (nang luc)) va ((hanh doi) OR (hang doi)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang ma hoi. hieu qua ((nhan luc) or (nang luc)) va ((hanh doi) OR (hang doi)) cua triet*.
