Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
anh tang » anh dang, anh sang, anh tong
anh nang » ganh nang, anh dang, anh sang
anh bang » anh hoang, anh quang, tinh bang
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 tieu xanh - ((((anh tang) OR (anh nang))) OR (anh bang)) va nhung cong dan than cao~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((((anh tang) or (anh nang))) or (anh bang)) va nhung cong dan than cao*.
