Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh vat » trinh van, trinh luat, sinh vat
dung cong » dung trong
manh toan » thanh toan, anh tuan
hien anh » hien hanh, thien anh, dien anh
vat dung » van dung, va dung, viet dung
dan than » dan chan, ban than, van than

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien anh - hanh trinh vat dung cong ((((manh toan) OR (tinh toan))) or (dan than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien anh - hanh trinh vat dung cong ((((manh toan) OR (tinh toan))) OR (dan than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien anh - hanh trinh vat dung cong ((((manh toan) OR (tinh toan))) or (dan than)) cau*".
