Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thien quan » trien quang, lien quan, thien van
duong manh » duong van
hanh dang » hanh dong, anh dang, hanh dung
manh toan » thanh toan, anh tuan, tinh toan
van dung » van dong, tin dung
toan tap » toan ban

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 xanh) or (thien quan)) - hanh dang ((van dung) OR (xay dung)) duong manh toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (thien quan)) - hanh dang ((van dung) OR (xay dung)) duong manh toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (thien quan)) - hanh dang ((van dung) OR (xay dung)) duong manh toan tap*".
