Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh tang » hanh trang, anh tang, hanh mang
tang chuc » cong chuc, tang cua, tang khu
chuc dang » chuc nang, chuc danh, thuoc dang
dang cong » dung cong
van thanh » ban thanh, van tuan
van toan » van tuan, van tan, manh toan

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 tang chuc dang cong ((van toan) OR (van thanh)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu tinh)) - hanh tang chuc dang cong ((van toan) OR (van thanh)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu tinh)) - hanh tang chuc dang cong ((van toan) OR (van thanh)) ban*.
