Perhaps you should try some spelling variations:
luan chinh » luan chi, hoan chinh, luat hinh
hanh tang » hanh trang, anh tang, hanh mang
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan cau » toan cao, toan ban, toan tap

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 (chu manh)) - hanh tang ((luan chung) OR (luan chinh)) cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chu manh)) - hanh tang ((luan chung) or (luan chinh)) cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chu manh)) - hanh tang ((luan chung) or (luan chinh)) cong san toan cau*.
