Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, chau tinh, kieu tinh
lieu tinh » trieu tinh, diep tinh, bien tinh
canh manh » lanh manh, canh tranh, cach mang
dung cong » dung trong
manh qua » manh quan, manh cua, danh qua
qua dung » quang dung, su dung, qua song
cong san » cong tac
phan cau » phan dau, phan cac, phan lap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (lieu tinh)) - canh manh qua dung cong san ((phan cau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (lieu tinh)) - canh manh qua dung cong san ((phan cau) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) OR (lieu tinh)) - canh manh qua dung cong san ((phan cau) or (phan tu))*.
