Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
trang va » tran van
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: ho ((chieu xanh) OR (chieu sang)) - hanh ((trang va) OR (hang va)) phuong cong danh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hanh ((trang va) OR (hang va)) phuong cong danh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh ((trang va) OR (hang va)) phuong cong danh toan cau*.
