Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh suat » trinh luat, trinh sat, trinh quan
thong cong » trong cong, tong cong, thong thong
hien xanh » hien hanh, hien nhanh, chieu xanh
san toan » van toan, manh toan, san doanh
dan toan » van toan, dan than, manh toan

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 xanh - hanh trinh suat thong cong ((((san toan) OR (xuan toan))) or (dan toan)) tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - hanh trinh suat thong cong ((((san toan) OR (xuan toan))) OR (dan toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh trinh suat thong cong ((((san toan) OR (xuan toan))) or (dan toan)) tap*".
