Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
thanh tran » thanh trang, thanh toan, thanh tra
thong cong » tong cong, thong thong, phong chong
tran tuan » tran xuan, tran quang, tran thanh
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
dan than » dan chan, ban than, van 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 - thanh tran tuan ((((thong cong) OR (trong cong))) or (dung cong)) dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh tran tuan ((((thong cong) OR (trong cong))) OR (dung cong)) dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh tran tuan ((((thong cong) OR (trong cong))) or (dung cong)) dan than cau*".
