Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhung cong » dung cong, thong cong, nhung don
hieu manh » chieu xanh, hieu nganh, dieu hanh
trinh cua » tinh cua, trinh luat, trinh quan
hang cong » dang cong, hang nong, bang cong
tan toan » tan tran, tap toan, van toan
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 ((hieu manh) OR (chieu tinh)) - hanh trinh cua ((nhung cong) OR (hang cong)) tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu tinh)) - hanh trinh cua ((nhung cong) OR (hang cong)) tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu tinh)) - hanh trinh cua ((nhung cong) OR (hang cong)) tan toan cao*.
