Perhaps you should try some spelling variations:
lanh tranh » canh tranh, lan tranh, hanh trinh
chieu tinh » trieu tinh, lieu tinh, chau tinh
lanh manh » lan anh, van manh, anh anh
cong hoan » cong hoa, dong hoa, cong san
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong san, cong thanh
phan cac » nhan cach, phan dau, 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 - ((lanh manh) OR (lanh tranh)) cua cong ((cong hoan) OR (cong tan)) phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((lanh manh) OR (lanh tranh)) cua cong ((cong hoan) or (cong tan)) phan cac~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((lanh manh) OR (lanh tranh)) cua cong ((cong hoan) or (cong tan)) phan cac*.
