Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
tang cua » mang cua, hang cua, tang luan
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
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 chu xanh - hanh tang cua nhung ((((cong dan) OR (cong san))) OR (cong thanh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh tang cua nhung ((((cong dan) OR (cong san))) or (cong thanh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh tang cua nhung ((((cong dan) OR (cong san))) or (cong thanh)) toan cao*.
