Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chuc danh » chuc nganh, thuc hanh, thuc dan
hanh mang » nhanh mang, hanh trang, nhanh lang
chu manh » ho manh, chu han, chu van
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
mang va » mang vua, hang va, bang va

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: theo ((((chuc danh) OR (chu manh))) OR (chuc nang)) - hanh mang va nhung cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chuc danh) or (chu manh))) or (chuc nang)) - hanh mang va nhung cong dan toan cau*.
