Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tran » thanh trang, thanh toan, thanh tra
quang dung » quang trung, ung dung, cuong dung
trong san » trong cac, cong san, dong san
phan cau » phan dau, phan cac, phan lap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) or (chieu tinh)) - thanh tran quang dung trong san ((phan cau) OR (phan tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu tinh)) - thanh tran quang dung trong san ((phan cau) OR (phan tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu tinh)) - thanh tran quang dung trong san ((phan cau) OR (phan tu))*".
