Perhaps you should try some spelling variations:
hanh manh » hanh mang, lanh manh, hoang manh
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tap
manh va » hanh va, anh va, minh va
chuc » thuc, chua, phuc

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 xanh) OR (chuc nang)) - hanh manh va nhung ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chuc nang)) - hanh manh va nhung ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chuc nang)) - hanh manh va nhung ((cong dan) OR (cong tan)) toan cau*.
