Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
thong cong » trong cong, tong cong, thong thong
hanh tinh » hanh trinh, thanh tinh, canh tinh
cua thong » cua thuong, cua khong, cua tong
cong can » cong san, cong tan, cong dan
can ban » van ban, toan ban
ban cau » bang cau, ban can, van cau

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 tinh) OR (nhanh tinh)) cua thong cong can ban cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - ((hanh tinh) OR (nhanh tinh)) cua thong cong can ban cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - ((hanh tinh) OR (nhanh tinh)) cua thong cong can ban cau*.
