Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
manh trung » manh tung, thanh trung, sinh trung
thong cong » trong cong, tong cong, thong thong
manh hung » anh huong
cap thong » cap tong, chap thuong, phap thong
cong tan » cong tac, cong san, cong thanh
tan chan » dan chan, ban chan, can chan
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: hoc ((chieu xanh) OR (chieu sach)) - ((manh trung) OR (manh hung)) cap thong cong tan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sach)) - ((manh trung) OR (manh hung)) cap thong cong tan chan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sach)) - ((manh trung) OR (manh hung)) cap thong cong tan chan cau*.
