Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
dang cong » dung cong
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
tang cua » mang cua, tang luan, thong cua
hang cua » mang cua, hang ca, huong cua
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 ((chieu xanh) OR (chieu sang)) - hanh ((tang cua) OR (hang cua)) dang cong danh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - hanh ((tang cua) or (hang cua)) dang cong danh toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - hanh ((tang cua) or (hang cua)) dang cong danh toan cao*.
