Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan
phan cau » phan dau, phan cac, phan tu
va nang » van nang, cam nang, kha nang
da nang » cam nang, kha nang, cao nang

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 ((chieu xanh) OR (cuu tinh)) - thanh trung ((va nang) OR (da nang)) cong dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (cuu tinh)) - thanh trung ((va nang) OR (da nang)) cong dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (cuu tinh)) - thanh trung ((va nang) OR (da nang)) cong dan phan cau*.
