Perhaps you should try some spelling variations:
hieu manh » chieu xanh, hieu nganh, dieu hanh
tuong cua » truong cua, huong cua, thong cua
phan cong » thanh cong
toc hieu » toc thieu, doc hieu, hoc thieu
tung cua » trung cua, tang cua, cung cua
dung cua » dung luan, dung cho
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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: toc hieu manh - thanh ((((tung cua) OR (dung cua))) OR (tuong cua)) phan cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - thanh ((((tung cua) OR (dung cua))) or (tuong cua)) phan cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - thanh ((((tung cua) OR (dung cua))) or (tuong cua)) phan cong dan toan cau*.
