Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu xanh » chieu xanh, hieu manh, thien anh
tuan hung » tran hung, luan hung, tuan dung
dien anh » tieng anh, dien dan
lan hung » van hung, luan chung, lan phuong
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan tap » toan ban

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

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (dien anh)) - thanh trung ((tuan hung) OR (lan hung)) cong tac toan tap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (dien anh)) - thanh trung ((tuan hung) or (lan hung)) cong tac toan tap*.
