Perhaps you should try some spelling variations:
xuan thanh » quan thanh, quang thanh, ban thanh
rong doanh » trong doanh, dong doanh, dung doanh
hien xanh » hien hanh, hien nhanh, chieu xanh
cua thang » cua thanh, xua thang, cua thuong
doanh van » doan van, doanh va, doanh ban
cua hang » cua dang, cua nhung, cua cong

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 - canh tranh ((((cua thang) OR (cua hang))) or (xuan thanh)) rong doanh van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - canh tranh ((((cua thang) OR (cua hang))) OR (xuan thanh)) rong doanh van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - canh tranh ((((cua thang) OR (cua hang))) or (xuan thanh)) rong doanh van ban*".
