Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
dang cong » dung cong
cong vinh » cong trinh, trong vinh, cong viec
vinh toan » tinh toan, hinh toan, minh toan
manh cua » doanh cua
toan ban » van ban
ban cua » ban quan

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 (chau tinh)) - canh ((manh cua) OR (ban cua)) dang cong vinh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chau tinh)) - canh ((manh cua) OR (ban cua)) dang cong vinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chau tinh)) - canh ((manh cua) OR (ban cua)) dang cong vinh toan ban*.
