Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cua truong » cua trung, xuan truong, xa truong
phuong dan » phuong danh, phuong doan, huong dan
dan chan » dan gian, dan ca, van chat
chan dau » phan dau, han dau, chan doan

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)) - canh tranh ((cua truong) OR (cac truong)) phuong dan chan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - canh tranh ((cua truong) OR (cac truong)) phuong dan chan dau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - canh tranh ((cua truong) OR (cac truong)) phuong dan chan dau*.
