Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chu » theo chieu, cho chu, chao chu
chu nang » chuc nang, chua nang, cuu nang
cap dung » ap dung, chan dung, cach dung
cao dung » cao dang, cao dong, cao ung
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap, toan tai
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 nang - thanh trung ((cap dung) OR (cao dung)) cong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu nang - thanh trung ((cap dung) OR (cao dung)) cong dan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chu nang - thanh trung ((cap dung) OR (cao dung)) cong dan ((toan cau) or (toan cao))*.
