Perhaps you should try some spelling variations:
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
dang cong » dung cong
theo chu » theo chieu, chao chu, theo yeu
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
cho chu » cho thue
dan van » dang van, doan van, dao van

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 chu) OR (cho chu)) xanh - ((hanh tang) OR (hanh mang)) cua dang cong dan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (cho chu)) xanh - ((hanh tang) OR (hanh mang)) cua dang cong dan van ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (cho chu)) xanh - ((hanh tang) OR (hanh mang)) cua dang cong dan van ban*.
