Perhaps you should try some spelling variations:
tran thanh » ban thanh, van thanh
quan thanh » ban thanh, van thanh
doanh phan » doanh nhan, doanh thanh, doanh luan
hien xanh » hien hanh, hien nhanh, chieu xanh
tong cong » trong cong, cong cong, dung cong
doan phan » toan phan, dan phan, doanh nhan

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 thanh) OR (quan thanh)) tong cong ((doan phan) or (doanh phan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - thanh ((tran thanh) OR (quan thanh)) tong cong ((doan phan) OR (doanh phan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh ((tran thanh) OR (quan thanh)) tong cong ((doan phan) or (doanh phan)) cau".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - thanh ((tran thanh) OR (quan thanh)) tong cong ((doan phan) or (doanh phan)) cau*.
