Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
chinh can » chinh ca, chinh cau, chinh ngan
chinh ban » chinh bao, chinh ngan, chinh luan
hang cong » dang cong, hang nong, bang cong
cong manh » cong danh, duong manh, cong thanh
ho chieu » theo chieu, hoc thieu, doi chieu

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 - hanh ((chinh can) or (chinh ban)) hang cong manh ((toan ban) OR (van ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - hanh ((chinh can) OR (chinh ban)) hang cong manh ((toan ban) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh ((chinh can) or (chinh ban)) hang cong manh ((toan ban) OR (van ban))".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh ((chinh can) or (chinh ban)) hang cong manh ((toan ban) OR (van ban))*.
