Perhaps you should try some spelling variations:
hanh trang » thanh trung, hanh trinh, minh trang
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
doc hieu » toc thieu, hoc thieu, hoc hien
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap
doi chi » doi khi

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: ((doc hieu) OR (doi chi)) xanh - ((hanh trang) OR (canh tranh)) cua nhung cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (doi chi)) xanh - ((hanh trang) OR (canh tranh)) cua nhung cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (doi chi)) xanh - ((hanh trang) OR (canh tranh)) cua nhung cong dan than cao*.
