Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
nang luong » nang song
luong cong » dung cong, trong cong, cong cong
hanh tran » thanh tran, hanh tram, thanh trang
ho trieu » mot trieu, 25 trieu, ho chieu
30 trieu » 25 trieu
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » toan cao, toan ban, toan tap

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 trieu) OR (30 trieu)) tinh - ((hanh tran) OR (hanh trang)) nang luong cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) or (30 trieu)) tinh - ((hanh tran) OR (hanh trang)) nang luong cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) or (30 trieu)) tinh - ((hanh tran) OR (hanh trang)) nang luong cong tan toan cau*.
