Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
luan dang » luan nang, luan danh, luan dong
dang cong » dung cong
anh dung » anh dong, sach dung, ung dung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 tinh) OR (chau tinh)) - ((anh dung) or (anh huong)) luan dang cong dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chau tinh)) - ((anh dung) OR (anh huong)) luan dang cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (chau tinh)) - ((anh dung) or (anh huong)) luan dang cong dan toan cao*".
