Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
cap duong » cau duong, cac duong, cap dung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
ap dung » xay dung, van dung

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 (chieu tinh)) - thanh trung ((cap duong) OR (ap dung)) cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - thanh trung ((cap duong) or (ap dung)) cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - thanh trung ((cap duong) or (ap dung)) cong dan toan ban*.
