Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh tung » thanh cong
tong cong » trong cong, cong cong, dung cong
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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 sang)) - ((thanh trung) OR (thanh tung)) cua tong cong dan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - ((thanh trung) or (thanh tung)) cua tong cong dan chan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - ((thanh trung) or (thanh tung)) cua tong cong dan chan cau*.
