Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh chua » tranh cua, trinh chuan, tranh chap
chau tinh » cuu tinh, ha tinh, cua tinh
chua nang » chuc nang, chua xang, kha nang
cong dan » cong san, cong tan, cong dong
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan tap
ho chau » ha chau, ho chu, o chau

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: ho chau tinh - hanh tranh chua nang ((cong dan) OR (huong dan)) ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - hanh tranh chua nang ((cong dan) or (huong dan)) ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - hanh tranh chua nang ((cong dan) or (huong dan)) ((toan cau) OR (toan cao))*.
