Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sang » chieu sach, chieu xanh, hieu lang
chieu tinh » trieu tinh, lieu tinh, chau tinh
tuan duong » tuyen duong, tuong duong, van duong
tuan dung » tran dung, tan dung, tuan dang
cong san » cong tac
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap

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 trung ((tuan dung) OR (tuan duong)) cong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu tinh)) - thanh trung ((tuan dung) OR (tuan duong)) cong san than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu tinh)) - thanh trung ((tuan dung) OR (tuan duong)) cong san than cau*".
