Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
tang cua » mang cua, hang cua, tang luan
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: theo ((chuc nang) OR (chieu tinh)) - hanh tang cua nhung cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc nang) or (chieu tinh)) - hanh tang cua nhung cong dan toan cau*.
