Perhaps you should try some spelling variations:
thien anh » thien danh, tien anh, thien thanh
hieu manh » chieu xanh, hieu nganh, hien hanh
dung cong » dung trong
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
mang cua » manh cua, dung cua, ban cua
cua dung » cua dang, cua dong, qua dung
phan cau » phan dau, phan cac, phan tu

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: hoc ((((hieu manh) OR (dieu hanh))) OR (thien anh)) - cach mang cua dung cong doan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((hieu manh) OR (dieu hanh))) or (thien anh)) - cach mang cua dung cong doan phan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((hieu manh) OR (dieu hanh))) or (thien anh)) - cach mang cua dung cong doan phan cau*.
