Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
chieu xanh » chieu sach, chieu sang, chieu tinh
hang cong » dang cong, hang nong, bang cong
chu xanh » chu manh, chua xang, chuc danh
trinh va » trinh van, trinh vat, trinh ve
toan tap » toan ban
ly toan » le toan, ly hoan, ly tran

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: cho ((chu xanh) OR (chieu xanh)) - hanh trinh va ((dung trong) OR (hang cong)) ly toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chieu xanh)) - hanh trinh va ((dung trong) or (hang cong)) ly toan tap~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chieu xanh)) - hanh trinh va ((dung trong) or (hang cong)) ly toan tap*.
