Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
danh thang » danh thanh, dinh thang, nhanh thang
thang van » tang van, thanh van, thong van
hang cong » dang cong, bang cong, thanh cong
hang nong » thang long, han tong
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh 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: hoc ((thieu xanh) OR (chieu xanh)) - danh thang van ((hang cong) OR (hang nong)) dan chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - danh thang van ((hang cong) or (hang nong)) dan chan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - danh thang van ((hang cong) or (hang nong)) dan chan cau*.
