Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thong cong » trong cong, tong cong, thong thong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trang cua » tang cua, trung cua, thang cua
tranh cua » doanh cua, manh cua
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: ho ((hieu manh) OR (chieu tinh)) - hanh ((trang cua) OR (tranh cua)) thong cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu tinh)) - hanh ((trang cua) OR (tranh cua)) thong cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu tinh)) - hanh ((trang cua) OR (tranh cua)) thong cong dan toan cau*.
