Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
dung cong » dung trong
30 trieu » 25 trieu
cua dung » cua dang, cua dong, qua dung
van tuan » van quan, van ban
van phan » van phong, van thanh, luan phan

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

• Performing a fuzzy search may retrieve terms with similar spellings: 30 trieu tinh - hanh trinh cua dung cong ((((van tuan) OR (anh tuan))) or (van phan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: 30 trieu tinh - hanh trinh cua dung cong ((((van tuan) OR (anh tuan))) OR (van phan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "30 trieu tinh - hanh trinh cua dung cong ((((van tuan) OR (anh tuan))) or (van phan)) cau*".
