Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
trang hoa » trang hoat, trung hoa, trang ha
tac doan » tap doan, tan doan, thai doan
doan cau » toan cau, doan dau, doan cap

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: hoc ((thieu xanh) OR (chieu xanh)) - hanh trang hoa ((nhung cong) OR (thong cong)) tac doan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - hanh trang hoa ((nhung cong) or (thong cong)) tac doan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - hanh trang hoa ((nhung cong) or (thong cong)) tac doan cau*.
