Perhaps you should try some spelling variations:
chien thuat » hien thuan, trien thuat, chien thuong
chieu tinh » lieu tinh, chau tinh, kieu tinh
cong ngang » cong nhan, cong quang, cong lang
ngang toan » nganh toan, dang toan, quang toan
ung cong » dung cong, luong cong, duong cong
toan cau » 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 (trieu tinh)) - hoach ((chien thuat) OR (thien thuat)) ung cong ngang toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (trieu tinh)) - hoach ((chien thuat) OR (thien thuat)) ung cong ngang toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (trieu tinh)) - hoach ((chien thuat) OR (thien thuat)) ung cong ngang toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - hoach ((chien thuat) OR (thien thuat)) ung cong ngang toan cau*.
