Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
dang cong » dung cong
cong danh » cuong danh, cong dan, cong thanh
khi xanh » khia canh, thi hanh, thi anh
cua dang » cua cong, cua ban
toan cao » toan tap
toan ban » van ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi khi xanh - hanh tranh cua dang cong danh ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh tranh cua dang cong danh ((toan cao) OR (toan ban))*.
