Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
dung cong » dung trong
cong danh » cuong danh, cong dan, cong thanh
danh toan » manh toan, anh toan, dan toan
chu xanh » chu manh, chua xang, chuc danh
hang cua » hang ca, huong cua, thong cua
mang cua » manh cua, dung cua, ban 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: chao ((chu xanh) OR (chieu xanh)) - hanh ((hang cua) OR (mang cua)) dung cong danh toan cao~.
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chieu xanh)) - hanh ((hang cua) or (mang cua)) dung cong danh toan cao*.
