Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
thanh tran » thanh trang, thanh toan, thanh tra
nhung tung » nhung dung, nhung vung, nhung huong
hien xanh » hien hanh, hien nhanh, chieu xanh
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 - ((thanh tran) or (canh tranh)) va ((nhung tung) OR (nhung tuong)) dan toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((thanh tran) OR (canh tranh)) va ((nhung tung) OR (nhung tuong)) dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((thanh tran) or (canh tranh)) va ((nhung tung) OR (nhung tuong)) dan toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((thanh tran) or (canh tranh)) va ((nhung tung) OR (nhung tuong)) dan toan cao*.
